regcomp.c: Refactor func so caller handles anomalies

S_grok_bslash_N() is refactored to not know about the strictness level
required by the caller, and to return things instead so that the caller
can decide what action to take.

This is in preparation for some changes in the caller's behavior in
future commits.

This has the effect of changing the parsing position or where a problem
occurs shown in a warning message.
