Some remarks:

 - The comparison between 5 and 6 does not seem fair, as you iterate in 6
but not in 5.

 - You don't use String#scan or #split which you are likely to need in
practice, because  you want to sift through complete documents and want to
treat all occurrences.

 - The differences between the check-first-char approach and the pure RE
approach are so insignificant that I'd not bother using the more complex
code.  I'd stick with pure RE based approaches and only try to optimize if
performance is bad.  (You mentioned premature optimization already... :-))

Kind regards
