Subject: Improved the ABORT logic to allow aborting consecutive "*" wildcards
X-Git-Url: https://mattmccutchen.net/rsync/rsync.git/commitdiff_plain/20b2e9cef70ef6ab6e28904a508569a86a5df7d0

Improved the ABORT logic to allow aborting consecutive "*" wildcards
back to a "**" wildcard.  Added optional debug code for recursion stats.
