Ordinarily, we keep the original helper implemented as a thin
wrapper that passes NULL as retun_error_code, which causes it to
die() on error for existing callers. But because we only have one
caller (and topics in-flight do not add new ones), we do not bother
with that.
The reasoning makes sense, at least to me.
We may want to add a comment about the behaviour upon error for the
helper function? I see resolve_gitdir_gently() does not do so and
the readers have to follow the callflow down to read_gitfile_gently()
which does have the comment, so perhaps we are OK without any.
Looks good to me.
