Subject: 28.0.50; RMAIL-summary changes colors after 99,999th message
Date: Fri, 15 Jan 2021 23:12:03 +0100

Hello,

my RMAIL-summary buffer uses different colors after the 99,999th
message.
Before, it uses green for unread messages and black for read ones, as
usual. From the 100,000th onwards, it uses normal black for unread; read
ones are displayed in usual black, except for the first 5 characters of
the second field (date) which are blue.


Thanks,
Andrea Monaco

It's clear that Rmail didn't expect to see more than 99999 messages in
any mail folder.

Does the patch below fix the issue?
