To get the behaviour you desire. you have to change this line:
complete -v -F _cd $nospace $filenames cd
Remove '$filenames', which will cause bash to no longer treat the
variable name as a filename, so it won't escape it.
Unfortunately, it will now also no longer append a slash to a path.
These are the kinds of trade-offs that bash's programmable completion
implementation requires, I'm afraid.

Please tell me which particular command is giving you this behaviour and which version of bash you are using.

Unfortunately, this causes an error to be printed if 'BASH_COMPLETION=blah' is executed for a second time. Redirection doesn't work on assignment, so this can't be silenced, except by using 'declare', which makes the variable local to the function.
BASH_COMPLETION is readonly, except in functions?
At the top of the script, whether or not it is being sourced
inside a function is checked. If so, then set the variables. If
not, then set them to be read-only.
Obviously, the better behaviour would be to make them
readonly all the time, but this is not implemented because
`declare -r' would then make those variables local to the
function. Here is a fix:
Use the `readonly' builtin. In fact, using this can mean that
the check for "$FUNCNAME" can be removed completely.
All done. :-)
Unless I've missed something, this would be a welcome
change in the next release. (I do source bash_completion
from a function.)
There is a completion script at worksintheory.org/file... which is much better than the one currently shipped with contrib. May be that could be included in the next release.
autocompletion of mutt aliases?
great project - there is one feature I'd like
the ability to autocomplete based on mutt's ~/.mutt.aliases file.
ie mutt [tab][tab]
gives a list of mutt aliases for recipients
I have tried to code this, but failed,
I think that implement bash completion for emerge
utility of Gentoo distibution is a good idea.
Emerge is similar to apt-get in Debian.

Thank you. A quick test showed that
indeed the "broken" behaviors do work again. This is
enough for my purpose and some
investigation will allow to selectively remove some of the
completions but not all.
Thank you for this constructive reply.
May I suggest to include both explanations (about the need
that the env variables do not change, and a way to turn the
feature off -- although the latter is actually a bash feature) in
the package documentation and on the project web page ?

These are set read-only, because it's bad to change them once they've been set. They are used later on and it's important that the value doesn't change. They can be set before the bash_completion script is run, however, and the original value will be honoured.

Yes, just run 'complete -r' and all completions will be removed, leaving just the default. However, I agree that this isn't the most useful way of achieving this, so I will consider the implementation of a better mechanism.

Well, e-mail works well, too. I agree that this forum isn't very efficient or convenient, so just e-mail me your comments instead. It would be nice to have a real mailing list, though. I'll consider setting one up.
