Nikita Nemkin 8d455809b0 string: Allow zero-length matches in all REGEX subcommands ...

The semantics mimic other languages like Python, Java, JS, etc.
To advance past a zero-length match, the search algorithm first
tries to find a non-zero alternative branch. If that fails, it
force-advances by 1 character.

Fixes: #13790, #13792, #18690, #26629
