Yikes.

I do not have enough info at this step in the series to judge if it
is sensible to force the :(glob) interpretation as default, but is
it something we would want to do commonly to flip the default per
Git subcommand?  If so, using the environment feels like a clunky
way to do that.

How about a two-patch clean-up before this step?

 (1) remove the handling of literal_global and friends that peek
     into various environment variables from prefix_pathspec(),
     which is a function that is repeatedly called for each pathspec
     element given from the command line, and move that logic to
     parse_pathspec(); pass necessary information down to
     prefix_pathspec() as parameter(s);

 (2) allow parse_pathspec() so that the caller can say "the default,
     when there is no environment variable given by the end user to
     tell us otherwise, is to :(glob)".
