...wouldn't we then want to do the same for match_name_as_path()?

I.e., this:

diff --git a/ref-filter.c b/ref-filter.c

 }

Also, I noticed that you declared it as "const int ignore_case" in
match_pattern(). That's not wrong, but we usually do not bother (it is
passed by value, so const-ness is irrelevant to the caller, and the
compiler can see inside the function that the value is not changed and
optimize appropriately).
