Bug#164755: debian-policy: mangled color sequences in fhs.txt

[Matej Vela <vela@debian.org>]

Package: debian-policy
Version: 3.5.7.0
Severity: minor
Tags: patch

groff 1.18 typesets bold and italic characters using ANSI color
sequences rather than backspaces, and `col -b' doesn't filter them
out:

                     1mFilesystem Hierarchy Standard -- Version 2.10m

                         Filesystem Hierarchy Standard Group
                               4medited24m 4mby24m 4mDaniel24m 4mQuinlan0m

Setting the GROFF_NO_SGR environment variable makes groff revert to
the old behavior, which `col -b' does handle:

(I used `$(MAKE) -C' to make it fit in 80 columns.)

Thanks,
