Not 100% sure but it might be more efficient to just implement the
automata that matches the pattern and feed events (i.e. chars) to it
while the user enters them.  Otherwise your regexp will grow pretty
complex as you have to provide options / alternatives for every
possible path the pattern can take. HTH
