#3848 jEdit ignores key combinations with AltGr modifier

When running jEdit on a Linux desktop with a German keyboard map, the following problem appears:

The jEdit shortcut for "Edit/Source/Go to Matching Bracket" is (by default) C+CLOSE_BRACKET. However, in the German keyboard map, the closing bracket is accessible using the AltGr+9 key combination. Thus, to achieve "C+CLOSE_BRACKET", the user would have to use the Ctrl+AltGr+9 key combination. However, this key combination is not recognized by jEdit, it instead recognizes "C+9" (as evidenced by testing this in the "Utilities/Options/jEdit/Shortcuts" section when trying to use Ctrl+AltGr+9 as shortcut). Thus, the Ctrl+AltGr+9 key combination is interpreted by jEdit as actually Ctrl+9, and both seem to be usable as interchangeably, while a separate Ctrl+AltGr+9 key combination is not accessible. Thus, the "C+CLOSE_BRACKET" key combination is not accessible, and thus, the jEdit shortcut for "Edit/Source/Go to Matching Bracket" is actually not accessible, while it should be accessible.

    I can confirm this bug in jEdit 5.0 using my German keyboard/installation though somehow with different details. AltGr-9, Ctrl-Alt-9, Ctrl-AltGr-9 and even Alt-AltGr-9 result in the keystroke CA-9]. Therefore the AltGr-key has lost is special functions which is a problem in a number of cases, e.g. Ctrl-Alt-q ("CA-q") vs. AltGr-q ("@").
