Hi,
I wrote this patch for project-switch-project, becasue it kept
highlighting the "wrong" charachters when using read-multiple-choice.
To take the example from the docstring: When evalutating
(read-multiple-choice "Continue connecting?"
'((?a "Always")
(?s "Session only")
(?n "No")))
with upper-case names instead of "always", "session only" and "no",
read-multiple-choice decides to highlight
Always Session only No
^ ^ (nothing here)
which I don't think it is always intended, just because one wanted to
capitalize the words. With this patch applied and a non-nil value passed
as the third argument, the first letters get highlighted as expected.
