Please report bugs via email to <bug-patch@gnu.org>.
If code has been duplicated (for instance with #ifdef OLDCODE ...
#else ... #endif), patch is incapable of patching both versions,
and, if it works at all, will likely patch the wrong one, and
tell you that it succeeded to boot.
If you apply a patch you've already applied, patch thinks it is a
reversed patch, and offers to un-apply the patch. This could be
construed as a feature.
Computing how to merge a hunk is significantly harder than using
the standard fuzzy algorithm. Bigger hunks, more context, a
bigger offset from the original location, and a worse match all
slow the algorithm down.
