nocaseglob affects regex matching in [[ but according to the man page only
nocasematch should:

nocaseglob
  If set, bash matches filenames in a case-insensitive fashion when
  performing pathname expansion (see Pathname Expansion above).
nocasematch
  If set, bash matches patterns in a case-insensitive fashion when
  performing matching while executing case or [[ conditional commands.


I don't know if it'd make sense to have case-insensitive glob matches and
case-sensitive regexes at the same time...  It may not be that useful and
even counterintuitive.
Anyway, it's probably better to either remove glob_ignore_case from line
67 in lib/sh/shmatch.c or document the actual behaviour, if intended.
