Because users 'out there' might run bash-completion in bash POSIX mode.  I
regard POSIX as just stricter bash script and supportable with little effort, so
I put it in the test suite to make sure bash-completion honours POSIX.  A
notable error is that POSIX doesn't allow a hyphen (-) in a function name,
whereas standard bash does allow:

    $ f-a() { echo foo; }
    $ set -o posix
    $ f-a() { echo foo; }
    bash: `f-a': not a valid identifier

Perhaps the test suite should test completions both with and without POSIX
mode...

Another solution - if bash-completion really demands noPOSIX :-( - could be to
disable POSIX on entering bash-completion and restore POSIX (if it was enabled)
on exit, but this 'on exit' is hard to catch...
