[Bash-completion-devel] _filedir only escaping whitespace when `-o filenames' is in effect?

[Freddy Vulto]

I just noticed `ssh -F <TAB>' doesn't escape spaces in filenames.
Further investigation showes that _filedir only works if `-o
filenames' is in effect:

    $ touch 'a b'
    $ _foo() { cur=$(_get_cword); _filedir; }
    $ complete -F _foo foo
    $ foo a<TAB>
    $ foo a b  # Incorrect, space isn't escaped
    $ complete -o filenames -F _foo foo
    $ foo a<TAB>
    $ foo a\ b  # This is correct

I was under the assumption that `_filedir' was to be trusted
anywhere, but it seems it isn't or am I overlooking something?
Otherwise, wouldn't it be nice to add an option to `_filedir' to
escape spaces?  Or better, create a new function `_compgen_filedir'
with this optional behaviour ;-)?  At least the following
completions have the same problem at the point where they call
`_filedir', because they don't have `-o filenames' ($filenames) in
effect:

    ../bash-completion/contrib$ for f in $(grep -l _filedir *)
    > do
    > grep -L \$filenames $f
    > done
