Log message:
fix infinite loops on regexps that match the empty word, which is
especially bad during runtime as we trap ^C.
For instance ${A:C/-*//g}. Problem found by rpe@
Do the same as other modern tools: advance by one char and repeat, so
that there's at most one empty word match at each position.
okay millert@
