 pts_0-linux.log, pts-0_xterm.log, pts-0_mlterm.log contains
"\x1b[30m" which makes foreground color black and immediately following
"\x1b[40m" which makes background color black.

 I think this problem isn't caused by mlterm but by the configuration
of mutt.

 How about adding a following line to ~/.muttrc

color normal default default

 I added k5 in mlterm 3.1.5.

 How do you change the cursor color ?
 Doesn't a following command work ?

echo -e "\x1b]12;red\x07"

 At first I designed and implemented the text selection behavior
like notepad.exe instead of xterm because of my preference.
 As a result, the internal implementation of layouting characters
depends heavily on this bahavior now.
 I'm sorry but a range of corrections is too extensive to change the
default bahavior.

 Indeed it is possible to ignore color sequences (ESC [ m) except black
and white, but is it necessary to support a monochrome terminal ?
 Furthermore I think the binary won't be smaller than expected.
