You're welcome!  I think it's useful for people to know what's coming.

The biggest reason is because external diff/patch utilities are often 
not available too Windows/IIS installations, and revision history is 
fairly important to the long-term functioning of a wiki.  Also, some
web hosting providers turn on PHP's safe_mode setting, which often restricts
access to external programs.  Finally, eventually I may want to have
PmWiki be able to better handle concurrent edits, and native diff/patch/
merge facilities could be a big help for this.

In 0.6 the diff/patch functions will likely be modularized (much like
search.php and upload.php), so that the wiki administrator can choose
a different diff/patch/versioning utility if desired.  PmWiki 0.6 will be 
distributed such that it can use either the PHP or the external diff/patch
functions.
