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.

VIMDIFF(1) General Commands Manual VIMDIFF(1) NAME vimdiff - edit between two and eight versions of a file with Vim and show differences SYNOPSIS vimdiff [options] file1 file2 [file3 [file4 [file5 [file6 [file7 [file8]]]]]] gvimdiff DESCRIPTION Vimdiff starts Vim on two up to eight files. Each file gets its own window. The differences between the files are highlighted. This is a nice way to inspect changes and to move changes from one version to an‐ other version of the same file. See vim(1) for details about Vim itself. When started as gvimdiff the GUI will be started, if available. In each window the 'diff' option will be set, which causes the differ‐ ences to be highlighted. The 'wrap' and 'scrollbind' options are set to make the text look good. The 'foldmethod' option is set to "diff", which puts ranges of lines without changes in a fold. 'foldcolumn' is set to two to make it easy to spot the folds and open or close them. OPTIONS Vertical splits are used to align the lines, as if the "-O" argument was used. To use horizontal splits instead, use the "-o" argument. For all other arguments see vim(1).
