I'm having a problem with certain characters causing the indentation in the
following lines to be messed up.
I found this problem in 4.6.2 originally, but made a git clone yesterday and
the problem seems to persist.
Screenshot of mutt to show you what I mean:
This does not happen with screen 4.4.0.
I haven't tried any versions between 4.4.0 and 4.6.2, but I have tested in
rxvt-unicode and xfce4-terminal with the same results. VTE based terms like
xfce4-term are usually pretty good at dealing with wide unicode characters.
I am starting screen with -U, tested with no ~/.screenrc and tried a few
different TERM settings to see if it would help. I have also tried a few of
the patches from Debian.
Something seems to have happened between 4.4.0 and 4.6.2, but a diff of the
two is around 17k lines long, so it's hard to sift through.
Thanks in advance for any pointers.
