Question about extdiff and kdiff3

[Clint Olsen]

Hi:

I took the example from the extdiff header in the extensions directory, and
it works well, except for one annoying aspect of kdiff3.  If you want to
skip all the beginning information dialog boxes about the directories
processed, you need to specify kdiff3 like so:

kdiff3 <file1> <file2>

Instead of:

kdiff3 <dir1 with extracted file> <dir2 with extracted file>

The opts. method allows for additional arguments, but I haven't figured out
a way to get the file argument into the command-lie for the diff tool.

Thanks,

-Clint
