Speed up skipwrap function

Short-circuit evaluation when `wrap_links` is True (the default).
Evaluating a boolean expression is much cheaper than searching a
paragraph for a match.

Any link present in the paragraph causes the wrapping to be skipped.
Instead of searching for all matches, stop at the first match.
