Even if a glob pattern filter is considered useful enough to be worth
special-casing, the glob capability should also be exposed via something
like your excluding_patterns constructor and additionally as a function
that can be called by another function intended for use as a callable
If it is not, then doing something like "files matching these glob
patterns except for those matching this non-glob-expressible condition and
also those files matching this second non-glob-expressible condition"
becomes painful because the glob part essentially needs to be
