Combi mode: Bang mode prefixes with len>1 (#542)
* Combi mode: Bang mode prefixes with len>1
This is required to match on modes that share a prefix.
Let 'power' and 'pass' be such modes for the following explanation:
Previously, only the first character of after the bang was compared,
so '!p' would always be matched to the 'pass' mode and there was no
way to limit selection in combi mode to the 'power' mode.
Now we can use prefixes of arbitrary length following the bang
such as '!po' (matches 'power' mode), or '!pa' (matches 'pass' mode).
Prefixes of length 1 are unchanged compared to the previous
behaviour, i.e. '!p' will still match 'pass'.
* Combi-mode prefixes should be utf-8 aware
