[Bash-completion-devel] Bug#655042: Should quickly check if already sourced and do nothing

[Josh Triplett]

Package: bash-completion
Version: 1:1.99-1
Severity: wishlist

Shell snippets to source the main bash_completion script typically
include some check to see if it has already run, to avoid sourcing it
again.  With older bash-completion, this check typically tested
$BASH_COMPLETION; newer bash-completion no longer sets that variable, so
the check uses $BASH_COMPLETION_COMPAT_DIR.  Either way, I'd suggest
that bash-completion should just include the appropriate check directly
in its main script, to avoid the need to write it when sourcing the
script.
