:command -complete option affects processing command arguments

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Define a command: `:command -nargs=1 -complete=dir Echo :echo <q-args>`
2. Run it: `:Echo $HOME`

What is the expected output? What do you see instead?

Expected: $HOME (would have seen this if there were no “-complete=dir” 
argument)

Seeing: /home/zyx

What version of the product are you using? On what operating system?

vim-7.3.456

Even if this is intended behavior, I do see its documentation nowhere between 
`:h :command-complete` and `:h command-completion-custom`.

Let's just document that behaviour for now:

Closing, as the documentation has been adjusted.
