[PATCH 1/2] howto: Suppress indentation with tabs

The AsciiDoc files in the 'howto' folder are installed as documentation
and AsciiDoc files are meant to be read and printed as is.  To quote the
AsciiDoc Home Page:

    AsciiDoc files are designed to be viewed, edited and printed
    directly or translated to other presentation formats using the
    asciidoc(1) command.

Tabs have the property of a configurable width and can thereby skew the
layout of a page and distort the meaning.  This is particularly a
problem when mixing lines with different indentation (space vs tab) in
code examples and ASCII art.

Prevent such a mix-up by prohibiting tab indentation entirely.
