Evaluate the following expression, then ask for help with ?.
(read-multiple-choice "Choose:"
'((?a "aaa")
(?b "bbb")
(?c "ccc" "a really long description of ccc")))
The description of choice "ccc" is misaligned in the help buffer:
------
Choose:
a: aaa b: bbb c: ccc
a really long
description of ccc
------
I expect the help buffer to look something like this:
------
Choose:
a: aaa b: bbb c: ccc
a really long
description of ccc
------
The patch below solves the problem, but I'm sure, it can be improved.
Additionally, I've attempted to write a test for this.
Thanks.
