I had forgotten about case-fold-search. It is, indeed, kinda annoying
to have to slap case-fold-search around various bits of code. Having
the flags actually be in the regexp itself would increase readability, I
think. (I mean, if you see #r"/foo/i" (or whatever) you know
immediately that it's case-insensitive, and don't have to have to read
upwards in the code to see what case-fold-search is at that point.)
Would this be possible to use interactively, in any way? I mean, if you
say (urrr, let's see)
C-u C-s /foo/u
you get the case-sensitive version of the search?
I mean, obviously not like that, but with a smarter syntax. :-)
C-u C-s ?r/foo/u
Eh. I don't know. Just contributing to the randomness. :-)
