   Some notes: by "glob," we mean `*` as a wildcard. So, this will need to:
   1. escape all special characters in PCRE Regex with `\` (except `*`)
   2. then replace any `*` with the PCRE `.*`.
   
   Also, `*` is a valid URL character. So this will need to also allow users to use `**` to indicate a literal `*` in the URL. So:
   - the above replacing should _not_ replace `**` with `.*.*`, but rather with `\*`.
   - we should add a sentence to the UI explaining that.

   Hm, * is valid in URL Path. So, maybe we need to make ** how people do literal *. Should be fine. And put a sentence saying that in the UI text.
