[PATCH] Correct spelling of 'REUC' extension

The new dircache extension CACHE_EXT_RESOLVE_UNDO, whose value is
0x52455543, is actually the ASCII sequence 'REUC', not the ASCII
sequence 'REUN'.

 I missed the patch that added this to C Git, so I got a bit
 surprised when an unresolved index started crashing inside of JGit.

 JGit is trying to do the right thing by ignoring the extension,
 since its name is all uppercase, but its still getting confused
 and barfing at the end of the file.  While trying to track it down
 I started scratching my head wondering what this 'REUC' extension
 was, and where it came from... only to find out its not actually
 documented in the sources, because the comment is wrong.

Thanks; applied.

It was originally meant to be "resolve undo conflicts" but the symbolic
name got too long with the last word.
