filemerge: do what the context __bytes__ does, but locally

str() here is clearly the wrong thing, and I think the code is clearer
when it doesn't just depend on the magic __{str,bytes}__ behavior.

I decided to grep around for \sstr\( and see what low-hanging fruit
that showed me. This was part of that hunt. That grep pattern still
has some things worth exploring.
