This documents the "Shell Command Language" so does not apply to
programs that want to process the wildcards themselves. The reason why
it is so easy to mistakenly assume that this globbing grammar applies
to all programs is because, on Unix, programs do not normally expand
any wildcards; the shell does that and passes the expanded file names
to the programs.

I'm curious to know how BUSH handles filename patterns.
