[DrJava] Line Enumeration

[Jim V. F. <big...@ri...>]

What a long, strange trip it's been.  After Charlie helped pull my head out 
of my rear, I got *an* implementation of getting a line number and column 
number out of a DefinitionsDocument fairly quickly.

I finished up some work that Erik and I were doing, and committed some code 
this afternoon that adds a DrScheme like listing of the line number and 
column number.

Apparently, the underlying calls are still very buggy.  Column is just all 
messed up, which means I will probably not rely on the helper methods 
already present to determine that info.

The line number, however, only seems to be wrong when using the up and down 
arrow keys, sometimes by as many as 20 lines on large files.

It would be easy to keep this out of a release, but if any of you have 
fifteen spare minutes, check out the code and see what I'm doing wrong.  I 
know you've wanted this feature in there, and we're very close.

Thanks all!

Jim
