After discussing it with Mark, I think it best to withdraw this proposal 
for now.  One of the main clients of the new API would be a revamped 
version of ICU transforms (transliterators), something which is not 
targetted for ICU 2.8.  The safest way to make sure that the regex API 
meets the anticipated needs of Translit is to design both together.

While exact best choice for an extended API isn't completely clear, it 
would be something that indicated whether a longer (or any) match could 
be obtained with addtional input to the string being matched.  The API 
may end up being a new matching function, rather than returning status 
regarding a previously attempted match.
