Maybe that gives extra motivation to drop the prefix, but it's still
misleading to count the prefix when comparing the lengths of proposed
subject formats. It makes no sense to say "this is shorter *if I remove
the prefix*", as the prefix can be equally removed from any format.

The first line of the commit message alone can take all the space
available for a mail subject in a reasonably set up MUA. There is no
"free" amount of text that you could safely use for filenames before the
message without hiding more important information.

The most important information should come first. If filenames are the
best way to do that then the commit message should start with them; if
they're not then the script should not force them to be added before
more relevant information.

That makes no sense even as an exaggeration when talking about mail
subject lines (you can select the contents of the subject but you cannot
force displaying it or other things in a particular way). The log
message is supposed to start with the most important information about
the commit so that's what should be shown at the start of the mail
subject.

How big a fixed size field? If you want a big enough field to hold two
different filenames that and the revision number already use up a
significant amount of space and either the first line of the commit
message would need to be very short or you'd need to have a lot of space
for the subject in your MUA.

It's mainly useful if you don't automatically sort mailing list mails to
subfolders (or do it according to the prefix, but I think fixing that
shouldn't be too hard for anyone). I'm not sure if anyone reads them
without automatic sorting.

I think it'd take less effort for people to use such abbreviations in
log messages when it makes sense than trying to automate their
generation...
