[wmii] simple tag permutations

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

Here's a little trick you can try, if you have the GNU BASH shell,
to get auto-completion for combinations of tags in wmiimenu. It uses
the {} braces permutation operator.

Cheers.

## the code (for wmiirc):

$MODKEY-Shift-t)
  tags=`wmiir read /tags`
  tags_csv=`echo $tags | tr ' ' ','`
  tags_joined=`eval "echo {$tags_csv}+{$tags_csv}"`
  xwrite /view/sel/sel/tags "`echo $tags $tags_joined | fmt -1 |
wmiimenu`" &;;

## how it works:

yantram.j0.s0.!510~$ wmiir read /tags
