core: display more verbose debug with two "-d" in command /eval

Now a single -d in command /eval shows less debug messages than previous
versions.

To get the same debug messages than previous versions, two -d must be used.

-Ein Ausdruck gilt als "wahr" sofern das Ergebnis weder NULL, nicht leer und von "0" abweichend ist.
+An expression is considered as "true" if it is not NULL, not empty, and different from "0".
-Für einen Vergleich werden Fließkommazahlen genutzt, insofern es sich bei beiden Ausdrücken um gültige Zahlen handelt, folgende Formate werden unterstützt:
+The comparison is made using floating point numbers if the two expressions are valid numbers, with one of the following formats:
-  - Integer (Beispiele: 5, -7)
+  - integer (examples: 5, -7)
-  - Fließkommazahl (Beispiele: 5.2, -7.5, 2.83e-2)
+  - floating point number (examples: 5.2, -7.5, 2.83e-2)
-  - hexadezimale Zahl (Beispiele: 0xA3, -0xA3)
+  - hexadecimal number (examples: 0xA3, -0xA3)
-Um einen Vergleich zwischen zwei Zeichenketten zu erzwingen, müssen die Ausdrücke in Anführungszeichen gesetzt werden, zum Beispiel:
+To force a string comparison, you can add double quotes around each expression, for example:
   50 > 100      ==> 0
   "50" > "100"  ==> 1
 
-Einige Variablen werden im Ausdruck mittels der Formatierung ${variable} ersetzt. Mögliche Variablen sind, nach Reihenfolge ihrer Priorität:
+Some variables are replaced in expression, using the format ${variable}, variable can be, by order of priority:

+  5. a string with max chars (format: "cut:max,suffix,string" or "cut:+max,suffix,string")
-     oder maximale Anzahl an Zeichen die auf dem Bildschirm angezeigt werden sollen (Format: "cutscr:Max,Suffix,Zeichenkette oder "cutscr:+Max,Suffix,Zeichenkette")
+     or max chars displayed on screen (format: "cutscr:max,suffix,string" or "cutscr:+max,suffix,string")

+  19. a hdata name/variable (the value is automatically converted to string), by default "window" and "buffer" point to current window/buffer.
-Das Format für hdata kann wie folgt aufgebaut sein:
+Format for hdata can be one of following:
-  hdata.var1.var2...: startet mit hdata (der Pointer muss bekannt sein) und fragt eine Variable nach der anderen ab (weitere hdata können folgen)
+  hdata.var1.var2...: start with a hdata (pointer must be known), and ask variables one after one (other hdata can be followed)
-  hdata[list].var1.var2...: startet hdata mittels einer Liste, zum Beispiel:
+  hdata[list].var1.var2...: start with a hdata using a list, for example:
-    ${buffer[gui_buffers].full_name}: der vollständige Name des ersten Buffers, in der verknüpften Liste aller Buffer
+    ${buffer[gui_buffers].full_name}: full name of first buffer in linked list of buffers
-    ${plugin[weechat_plugins].name}: Name der ersten Erweiterung, in der verknüpften Liste aller Erweiterungen
+    ${plugin[weechat_plugins].name}: name of first plugin in linked list of plugins
-  hdata[pointer].var1.var2...: startet hdata mittels einem Pointer, zum Beispiel:
+  hdata[pointer].var1.var2...: start with a hdata using a pointer, for example:
-    ${buffer[0x1234abcd].full_name}: vollständiger Name eines Buffers und des dazugehörigen Pointers (kann in triggern benutzt werden)
+    ${buffer[0x1234abcd].full_name}: full name of the buffer with this pointer (can be used in triggers)
-Die vorhandenen Namen für hdata und Variablen sind in der "Anleitung für API Erweiterung", Bereich "weechat_hdata_get". beschrieben
+For name of hdata and variables, please look at "Plugin API reference", function "weechat_hdata_get".

-                ==*  pasuje do maski, rozróżnia wielkość znaków (dzika karta "*" dozwolona)
+An expression is considered as "true" if it is not NULL, not empty, and different from "0".
-                !!*  NIE pasuje do maski, rozróżnia wielkość znaków (dzika karta "*" dozwolona)
+The comparison is made using floating point numbers if the two expressions are valid numbers, with one of the following formats:
-                =*  pasuje do maski, nie rozróżnia wielkość znaków (dzika karta "*" dozwolona)
+  - integer (examples: 5, -7)
-                !*  NIE pasuje do maski, nie rozróżnia wielkość znaków (dzika karta "*" dozwolona)
+  - floating point number (examples: 5.2, -7.5, 2.83e-2)
-                ==-  jest zawarte, rozróżnia wielkość znaków
+  - hexadecimal number (examples: 0xA3, -0xA3)
-                !!-  NIE jest zawarte,rozróżnia wielkość znaków
+To force a string comparison, you can add double quotes around each expression, for example:
-                =-   jest zawarte, nie rozróżnia wielkość znaków
-                !-   NIE jest zawarte, nie rozróżnia wielkość znaków
-
-Wyrażenie jest uznawane za „prawdziwe” jeśli nie jest NULL, nie jest puste, oraz różni się od "0".
-Porównania dokonuje się z użyciem liczb całkowitych jeśli oba wyrażenia są liczbami całkowitymi, w jednym z następujących formatów:
-  - liczby całkowite (przykłady: 5, -7)
-  - liczby zmiennoprzecinkowe (przykłady: 5.2, -7.5, 2.83e-2)
-  - liczby szesnastkowe (przykłady: 0xA3, -0xA3)
-W celu wymuszenia porównywania ciągów, należy umieścić każde wyrażenie w cudzysłowie, na przykład:
   50 > 100      ==> 0
   "50" > "100"  ==> 1
 
-Niektóre zmienne w wyrażeniach są zamieniane, poprzez zastosowanie formatu ${zmienna}, według priorytetu zmienną może być:
+Some variables are replaced in expression, using the format ${variable}, variable can be, by order of priority:

+    ${buffer[0x1234abcd].full_name}: full name of the buffer with this pointer (can be used in triggers)
-Nazwy hdata i zmiennych, można znaleźć w  „Opisie API wtyczek”, funkcja "weechat_hdata_get".
+For name of hdata and variables, please look at "Plugin API reference", function "weechat_hdata_get".
