Does this "know" already to do a simply string compare to test the 
resulting regex? (And/or does compiling of the regex's already handle 
that case for any regex that is effectively a fixed string?)

For me that has been the main reason to use a fixed-string pattern type.

Are these supported mainly because the pattern may be coming from user 
input, or because internally the match implementation can be more 
efficient? If the latter, I'm not sure it is worth even having a "glob" 
pattern type. If the former, then supporting as many shell-isms as 
possible is probably useful.
