Yeah, I felt the same way. We could refactor this out into two separate
functions, one which returns an ssize_t and one which actually
allocates, but I'm not sure it makes a huge amount of sense with just
one caller. The allocation is relatively small, and I've tried to make
sure it's called exactly once per patch so as not to be wasteful and
inefficient.

I struggled with this variable name, as I'm sure you guessed. I could
call it "has_suffix" or something similar. I have mixed feelings about
naming pointer variables like booleans since it makes things prone to
misreading, but I think that might be the sanest thing to do here. I can
certainly do "p" as well.

I'll see if there are other comments about directions to take here, and
then reroll.
