You may want to split the changes to 't/helper/test-parse-pathspec-file.c'
into its own patch, since those changes are not potentially controversial.

The remainder of this patch follows a pattern that I used in a patch that
was rejected; see https://public-inbox.org/git/e6796c60-a870-e761-3b07-b680f934c537@ramsayjones.plus.com/, et seq.

Actually, I have a patch somewhere which suppressed the sparse warning
for the '= { 0 }' token sequence used in these initializations. However,
I don't seem to be able to find them at the moment! :(

[Luc, this topic came up on the sparse and kernel mailing-lists at one
point, but I didn't get around to posting my patch to the list - something
came up. Hopefully, I will find some time to find it and post it soon.]

ATB,
Ramsay Jones
