bash completion doesn't perform filename processing for ssh -i

[Adam Simpkins]

Binary package hint: bash

In /etc/bash_completion, the completion for the "ssh" command doesn't use the
"-o filenames" option. As a result, filename processing isn't performed on the
completed results. (In particular, this includes adding a trailing slash to
directory names.)

This is nice for most cases, but ssh's "-i" option does take a filename
argument. The lack of filename processing can be rather annoying when trying
to specify a key in a deep path.

Unfortunately, I'm not sure if bash provides an easy way to enable the
"-o filenames" behavior only for certain arguments. I think it may only be
possible to set it on a per-command basis. Therefore the only way to fix this
may be to manually perform this processing in the _filedir() function in
/etc/bash_completion (or perhaps just in the _ssh() function).

Either way, this is a very low priority bug.

I'm not sure this is even fixable without changes to bash itself...

What version of bash-completion does this occur with? I have bash 4.1-2ubuntu4 and bash-completion 1:1.2-2ubuntu1 on Maverick amd64, and when I type "ssh -i ~/.ssh/" and then press tab, I see the options:

ek@Apok:~$ ssh -i ~/.ssh/
~/.ssh/id_rsa ~/.ssh/id_rsa.pub ~/.ssh/known_hosts

When I type "ssh -i ~/.ssh/id_rsa." and press tab, it expands to "ssh -i ~/.ssh/id_rsa.pub". So bash-completion works correctly for ssh -i on my system.

the function i wrote for ssh-add in #376546 would work here.

further to the previous comment, here is the modification to the ssh bash_completion to handle -i searching for keys

This depends on the _ssh-add as per the (second) attachment in bug #376546
