Trying to replace all occurrences of "debug_client" with "DebugClient", when the "Whole word" option is selected in the Search&Replace dialog, causes also partial word replacements. E.g. both of the following were replaced:
Note that in the 2nd line, debug_client does not appear as a whole word.
The _replace() method in SearchAndReplace.java file noWordSep is assigned with wordBreakChars. So i changed it to assign noWordSep
