Oh, git mailsplit must have been introduced after I looked into this the
last time. Nice.

The downside is that this doesn't work on patches piped from the MUA,
because git mailsplit expects an mbox. Fail.

I notice that you indent most of the function in the for loop, perhaps
that's an indication you should turn this one into a single patch
helper, and do the mailsplit in a new dim_apply_branch that only does
that?

Please use $(...) instead of `...`. Didn't test, but I think shellcheck
would complain.

I think you should do $(find $dir | sort) instead of ls.

Otherwise seems like this should work.

BR,
Jani.
