Uh, what version of patch are you running?  On my system (which is cursed with
the System V Short Filenames From Hell), patch is smart enough to not try to
use ".orig" as the extension for the original file; instead it uses tilde.
It also uses "#" as the suffix for the reject files instead of ".rej".  Hence
you only need restrict yourself to 13-character filenames.  It probably would 
be polite to restrict it slightly further, to 12 chars, in case the user wants
to keep his source under RCS or SCCS, which add 2 chars to the filename (",v" 
at the end for RCS, "s." at the beginning for SCCS).  Still, one hardly needs
to be so restrictive as to limit oneself to 9-character names.
