#4 Support "strike-through" attribute

[inof]

Currently, JOE supports several attributes in color files (.jcf): bold, inverse, blink, dim, underline, and italic. However, strike-through (sometimes called crossed-out) is missing. I would greatly appreciate it if that could be added. The keyword could be just "strike" or "crossed". The ANSI escape sequence for that attribute is ESC[9m. This is according to the standard ISO 6429. It is not supported by xterm or rxvt (as far as I know), but it's supported by some other terminal emulators, for example mintty (cygwin); see the attached screenshot. You can easily test if it's supported with this shell command: echo $'\e[9mTEST\e[m'

Thank you very much!

This is now in Mercurial: 'stricken' and 'dunderline'. Also \s and \z in help screens and status line.

Great, thank you very much!
Meanwhile I found out that xterm supports these attributes, too, but only when using true-type fonts (it does not seem to work with old-style bitmap fonts). I guess it's the same with rxvt since it is derived from xterm.
Oh by the way: Sometimes I have the need to make tab characters (slightly) visible in certain types of files. Using strike-through would be a nice way to do that, using a syntax file with strike-through dark grey on black for tab characters.
