stupidity: a slighlty less horrible wine tree diff gizmo

[Greg Turner]

Still up to the same old stupid bash tricks... but implemented slightly
better.  This will still have to be manually maintained to
remain useful as wine's directory structure evolves, just
like the old "version" of this awfulness.  Use at your own
(very real) risk as these are almost untested.  License is bugroff.

This version has better provisions for in-source compilation, 
runs in only one pass, and is cwd/location independant.  It
should also be a lot easier to maintain than the previous try

winetreediff (a script to filter out impossible-to-glob patterns
  and perform the real processing.  Note the hard-coded path to
  winetreediff_excl.  Change it to match where you put it.
  Needs the x bit, of course.)

still hardly a work of art.  but ought to generate diffs
between trees ready for submission to wine-devel, no cvs
needed.  For example, I use this as follows to update my
horribly out-of-sync wine tree with the latest changes
from cvs:

        .../wine> cd ../wine.test
   .../wine.test> winetreediff ../wine.vanilla | wc -l

0 
        .../wine> # great, these trees are identical w.r.t. winetreediff.
        .../wine> cd ../wine.vanilla
.../wine.vanilla> cvs -qz4 up -dPA

[cvs does something]

.../wine.vanilla> # generate the difference between "../wine.test" and "."
.../wine.vanilla> winetreediff ../wine.test > ../wine/mydiffs/cvsupdate.diff
.../wine.vanilla> cd ../wine.test
   .../wine.test> patch -p0 < ../wine/mydiffs/cvsupdate.diff

[ goes fine ]

   .../wine.test> cd ../wine


Now I have a nice diff expressing the difference caused by the
CVS update.  If I am concerned about it, I could run

        .../wine> patch -p0 --dry-run < mydiffs/cvsupdate.diff

To see what the damage will be, otherwise, just

        .../wine> patch -p0 < mydiffs/cvsupdate.diff

would bring me up-to-date.

LIMITATIONS:

  o Dangerous if used incautiously.
  o Breaks if wine changes.
  o Probably Buggy.
  o Only supports "." and "/" characters in directory argument.
  o Creates and destroys temp files named delme.diff and delme2.diff.
    (Should at least use something more obscure.)
  o Prefers (requires?) a matching directory structure between the two trees.
