[PATCH 3/5] restrict the patch filtering

[Don Zickus <dzickus@redhat.com>]

I have come across many emails that use long strings of '-'s as separators
for ideas.  This patch below limits the separator to only 3 '-', with the
intent that long string of '-'s will stay in the commit msg and not in the
patch file.

I purposedly separated this patch out because I wasn't sure if anyone would
have objections to it.  I tested it on numerous emails with and with patches
and didn't see any issues.
