Summary: Smarter End Key

Initial Comment:
For a class project, my partner and I implemented the Smarter End Key feature request: 

http://sourceforge.net/tracker/index.php?func=detail&aid=1903596&group_id=588&atid=350588

We added an option to the Editing Options menu to create a comma separated list of comment delimiters. On hitting the end key, it will move the caret to after the last non-whitespace character before a delimiter. 

For example, if Delimiter list is: //, /*


Before:
this| is some text. //This is a test<space><space>

After End x 1:

this is some text.| //This is a test<space><space>

After End x 2:

this is some text. //This is a test|<space><space>

After End x 3:

this is some text. //This is a test<space><space>|

If no delimiters are set, then the smart end function should work as it does currently.

Any comments, suggestions, or responses are greatly appreciated.

Can I suggest an improvement. Rather than requiring a list of comment
delimiters, use the pre-existing syntax awareness of jEdit -- for its
syntax highlighting. That is, surely there is some way to read the syntax
type that the cursor is on.

I have implemented this in the past for another editor (Ed for Windows).
The logic is fairly simple, something like:

Go to end of line
while (not at the start of the line, and character left of cursor is
whitespace or comment)
{
    Go left one character
}

(I'd be interested in doing this myself for jEdit, but currently have
neither the time nor the Java skills.)
