git config --get-regexp exit status

I made a patch that uses "git config --get-regexp" to get the
description and stgit.stackformatversion options for all branches at
once, and ignore the "protected" flag that I don't use. With this
change, I'm almost down to half a second, which almost makes it
usable.

One thing that annoyed me what that "git config --get-regexp" will
return zero, one, or more matches, which are all valid reponses. But
it treats the zero-match special and return an exit status of 1.

Is that a conscious choice, or just an effect of how "git config
--get" works?

Since zero matches isn't really an error, I would like the exit status
to be 0. At least for this use case :-)
