The attached sequence of patches adds (?dlu:...) regex modifiers, which
we have discussed at great length on this list. There's also a little
comment/doc cleanup for the (?^...) patch. Thanks to that patch, no
tests that look at stringification need to change to accommodate these.
The (?u...) modifier is recognized by this patch, but it actually
doesn't do anything (except turn off the other modifiers) yet. When
this patch, revised as necessary, is incorporated, I'll rebase and
resubmit the patch that starts to use it.
I have a concern that something needs to be done with:
that I haven't done, as code was changed in those for the /r modifier
added this summer. However, I don't see what that should be, and my
experiments don't show anything necessary.
