Some time between 23.0.60 and 23.1, a minor annoyance was introduced into
rmail. When case-fold-search is nil, the dates in the rmail summary are
all rendered as "??????".
This is because of the regular expression in rmailsum.el at line 529. A
string such as "May" doesn't match the regular expression:
[adfjmnos][acepou][bcglnprtvy]
because the capital letter doesn't match when case-fold-search is nil.
The easy work-around is to turn on case-fold-search, but it would be nice
to fix it properly, so that rmail works no matter what the user-set value
is. It may also be useful to do a quick scan of the .el files to see if
there are other cases where a nil value of case-fold-search might break
some modes or behaviours.
