Bug#923022: console-setup ships minified shell scripts

[Wookey <wookey@debian.org>]

Package: console-setup
Version: 1.189
Severity: normal
Tags: patch

/bin/setupcon and /usr/bin/ckbcomp-mini are both shell scripts that
are minified (preprocessed to remove comments, whitespace and
indenting) before being shipped in the udeb.

/usr/lib/base-installer.d/20console-setup and 
usr/share/console-setup/keyboard-configuration.config

setupcon is a 38K script before minifying and 22K afterwards. It's
extremely difficult to read to work out what on earth it is doing when
in that state, and this is sometimes necessary (e.g. when debugging
debian-installer). ckbcomp-mini goes from 5.4K to 3.3K keyboardconfiguration from 47K to 44K

The debian config and postinst scripts get the same treatment (in the
conventional and udeb packages

Why are we minifying these scripts? Perhaps it made sense once to
squeeze the size of console-setup by a few K (maybe 24?), but it seems
very unlikely to be useful any more, given the cost of making
comprehension of the code almost impossible.

Attached is a patch to stop doing this. (It makes the udeb 6K bigger)
