patch 9.0.1827: xxd: no color support
Problem: xxd: no color support
Solution: Add color support using xxd -R
Add some basic color support for xxd
The hex-value and value are both colored with the same color depending
on the hex-value, e.g.:
0x00 = white
0xff = blue
printable = green
non-printable = red
tabs and linebreaks = yellow
Each character needs 11 more bytes to contain color. (Same color in a
row could contain only one overhead but the logic how xxd creates colums
must be then changed.) Size of colored output is increased by factor of
~6. Also grepping the output will break when colors is used.
Flag for color is "-R", because less uses "-R".
Color uses parameters auto,always,never same as less and grep (among
others).
E.g.
xxd -R always $FILE | less -R
Add some screen-tests (that currently on work on linux) to verify the
feature works as expected.

.TH VIMTUTOR 1 "2001 April 2" .SH NAME vimtutor \- the Vim tutor .SH SYNOPSIS .br .B vimtutor [\-g] [language] .SH DESCRIPTION .B Vimtutor starts the .B Vim tutor. It copies the tutor file first, so that it can be modified without changing the original file. .PP The .B Vimtutor is useful for people that want to learn their first .B Vim commands. .PP The optional argument \-g starts vimtutor with gvim rather than vim, if the GUI version of vim is available, or falls back to Vim if gvim is not found. .PP The optional [language] argument is the two-letter name of a language, like "it" or "es". If the [language] argument is missing, the language of the current locale will be used. If a tutor in this language is available, it will be used. Otherwise the English version will be used. .PP .B Vim is always started in Vi compatible mode. .SH FILES .TP 15 /usr/local/lib/vim/tutor/tutor[.language] The .B Vimtutor text file(s). .TP 15 /usr/local/lib/vim/tutor/tutor.vim The Vim script used to copy the .B Vimtutor text file. .SH AUTHOR The .B Vimtutor was originally written for Vi by Michael C. Pierce and Robert K. Ware, Colorado School of Mines using ideas supplied by Charles Smith, Colorado State University. E-mail: bware@mines.colorado.edu (now invalid). .br It was modified for .B Vim by Bram Moolenaar. For the names of the translators see the tutor files. .SH SEE ALSO vim(1)
