SGR 21: double underline
Last modified: 2017-12-05 20:25:51 UTC
http://en.wikipedia.org/wiki/ANSI_escape_code says SGR 21 is: Bold: off or Underline: Double bold off not widely supported, double underline hardly ever In vte it's "bold off". xterm-305 added this as "double underline" (i.e. double-width, rather than two lines).
This is now being addressed in bug 721761, let's mark as dup. *** This bug has been marked as a duplicate of bug 721761 ***
