In cases like this, it's probably acceptable to post the two together,
since BC3.1 fixes aren't really "features".  I usually check out the
diffs manually and apply them very carefully when I get them, so you
don't worry about errors from that part of the process (but I do, of
course).

What you can do is insert a line just before each diff chunk (patch
ignores them) stating what each chunk is for, so that I can separate
them myself if I need to.  Example:

Previous:

*** foo Mon Apr 26 09:57:37 1993
--- foo2        Mon Apr 26 09:57:37 1993

New:

*** foo Mon Apr 26 09:57:37 1993
--- foo2        Mon Apr 26 09:57:37 1993

This is the header part

These are the actual changes
