[Bash-completion-devel] Fixed competion of '~' and '~xx' in _filedir_xspec()

[wonder.mice]

Hello,

I would like to fix issue with expanding '~' by several completion scripts:
#489720 [m|U☹|=↝] [bash-completion] bash-completion: Please do not 
expand leading tildes
#521406 [m|U☹|=↝] [bash-completion] bash-completion: leading tilde 
always expanded
please do not expand leading tildes 
https://bugs.launchpad.net/bash-completion/+bug/324505

As I understand, the problem is in _expand() function that is not always 
correctly used.
For example, in _filedir_xspec() it expands '~' regardless to bind 
-v|grep expand-tilde option.

This patch will not solve problems described above.
I'm very new in bash and completion and I want to understand that I got 
right direction.

That patch fixes simple problem:
$ vim ~mi<TAB>
will not expand to
$ vim ~mice/

----

Use _tilde() to complete '~' and '~xx' like it done in _filedir().
