Wow, 1997 --- seems like a time long ago.
As I remember, I crudely coded up a fix for the complaint --- that's the
way we did it back then. :-)
There probably wasn't a lot of discussion, if any --- people complained,
and we coded to fix the complaint. In hindsight, I should have told
them the API was working properly, but the idea of telling a user they
were wrong wasn't something we did back then --- we needed every user we
could get.
My guess is that the email reports from May, 1997 were in my mailbox,
and in Novemeber I saw it again (I was a volunteer then) and I coded up
the fix, posted it to the lists, then applied it. No one said anything
about it, so it stayed in.
Strange no one complained about it until now. I suppose that is because
few folks use that function _and_ upper-case identifiers, as you
mentioned. We could code the proper behavior, post a mention on
general, and document it in the release notes, or wait for 7.5, or do
nothing.
