I think the best way of doing this would be to add PCRE2_ASCII_CASELESS to the
main options, because having two separated flags seems very untidy. There are
only two bits left in the main options, so I am slightly reluctant, but on the
other hand leaving them unused just in case something more important comes
along could last for ever. Zoltan, what do you think? Implementing this would
need changes to JIT as well as the interpreters.
