bug#46332: Eshell color control characters not displayed correctly

[Morgan Smith]

Hello Emacs maintainers!


So I have my pager set to cat and in eshell I type `git log` and after a
while (1000 - 2000 lines) it starts to show the control characters
verbatim instead of coloring the characters. So it works initially but
then breaks down after a bit. This applies to all commands but git log
is a good one to use for testing.

I did a quick git bisect to figure out when the problem occurred and it
seems commit 2e2a8e5491bc6259a9ebe8c703c1c501307953e2 is the
offender.

I can confirm the bug still exists as of commit
0484879d3b0f81222bacbc3c9655d1cfcdb5d321.


Thanks,

Morgan
