It's completion-ignored-extensions, but it's not the problem because that
variable will never cause a "no match": if the only match is a file with
one of the ignored extensions, then the file is still selected.
I.e. those ignored files are only ignored as long as there's some other
file that matches the current prefix.  So it doesn't really ignore, but
just gives preference to other files.
