[PATCH 1/3] console_codes.4: \e[21m is now underline

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since 65d9982d7 (4.17), it follows xterm rather than common sense and
consistency, being the only command 1..9 where N+20 doesn't undo what
N did.  As libvte 0.51.90 got changed the same way, this behaviour will
probably stay.
