I considered suggesting that, too, but it means that everywhere that
checks for PATHSPEC_LITERAL must _also_ check for literal_global (e.g.,
if they were deciding to feed the result to fnmatch). Whereas if we
catch it at the parse_pathspec layer, then the consumers of the pathspec
just need to check the one flag.

I dunno. I haven't kept up very well with your work in this area, so you
probably have a better sense than I do of what would be the most
