Subject: [PATCH] metacharacters in directory names

* quote metachars in tab completions because bash doesn't, or at least,
  I can't figure out how to tell it to yet.
* tell zsh NOT to quote metachars in tab completions because it does, by
  default. this is irritating, as i'm sure it's better than me at it.
* do the irritating metachar quoting that's been a PITA on a copy
  of the variable, so we can return the original, because gsub modifies
  in place.

TODO: if we're going to be taking over metacharacter quoting, we ought
to do it less halfhazardly
