Documentation

Show fine differences in the two regions BEG1..END1 and BEG2..END2.

PROPS-C is an alist of properties to put (via overlays) on the changes. PROPS-R is an alist of properties to put on removed characters. PROPS-A is an alist of properties to put on added characters. If PROPS-R and PROPS-A are nil, put PROPS-C on all changes. If PROPS-C is nil, but PROPS-R and PROPS-A are non-nil, put PROPS-A on added characters, PROPS-R on removed characters. If PROPS-C, PROPS-R and PROPS-A are non-nil, put PROPS-C on changed characters, PROPS-A on added characters, and PROPS-R on removed characters.

If non-nil, PREPROC is called with no argument in a buffer that contains a copy of a region, just before preparing it to for diff. It can be used to replace chars to try and eliminate some spurious differences.
