Can an stgit patch file (or the leading pathname for that matter) have IFS

Portability tip from an old timer: do not create a new empty file with
"touch" (only use that command to update the timestamp of an existing
file).
Instead say

Can any token that match Author other than the initial "Author: " appear
on this line?
Since we rely on Perl but not awk in core-ish part of the scripted
Porcelains, it might be a good idea to write this in Perl as well.
