           Summary: case sensitive options are broken
           Product: libraries
           Version: unspecified
          Platform: PC

            Status: NEW

The way case sensitivity is handled in the current code is broken:

* During parsing the case-sensitive argument applies only to
  character sets.
* During matching the case-sensitive argument applies only to
  non character sets.

I believe the right thing is to get rid of the case-sensitive
argument for matching and make the one for parsing "just work".  It
will have to just work anyway, once on-the-fly flags like (?i) are
implemented.

Probably this means storing a default-case-sensitive flag in the
regex, and then maintaining a dynamic flag during matching, but I
haven't thought it through yet.
