[Bash-completion-devel] Bug#776160: bash-completion: /etc/profile.d/bash_completion causes warnings with '-o nounset'

[Michael Gold]

Package: bash-completion
Version: 1:2.1-4
Tags: patch

/etc/profile.d/bash_completion accesses some variables like $BASH and
$PS1 that may be unset, which will produce a warning or error if the
(POSIX-standard) 'nounset' option is enabled.  See #776154 for details.
E.g.,
	$ set -u
	$ . /etc/profile.d/bash_completion.sh
	bash: BASH_COMPLETION_COMPAT_DIR: unbound variable

A patch is attached, which prevents errors when not loading completions
(i.e. in non-bash shells; but some of the completion scripts use unbound
variables).  I also quoted bmajor and bminor to guard against weird IFS
values.
