Great indeed!
More comments later. First nit: please review the various regex_replace
overloads vs inline: if I'm not misreading the diff I see large ones
inline and small ones out of line!?! Should we have a regex.tcc?
Also, old story about ChangeLogs ;) This is not ok:
* include/bits/regex.h: Implement match_results::format and
regex_replace.
use something like:
* include/bits/regex.h (match_results::format, regex_replace):
Implement.
That is, function names *always* between round brackets.
