fixes a couple of regexps, the suite showed warnings about them

A couple of things worth mentioning here:

 - "{" is a metacharacter, should be escaped
   if it is meant to match a "{". The code
   worked, though, because the regexp engine
   is tolerant to this, but issued warnings.

 - gsub accepts a string as first argument.
   That's the best idiom to use when your
   pattern has no metacharacters, since gsub
   interprets the string as an exact substring
   to look for, rather than a regexp. The
   benefit is that your pattern is crystal
   clear and needs no backslashes.
