Subject: [PATCH] awful.prompt: add trail space in prompt_text_with_cursor()

Adds a trailing space after text if cursor position < text length to
prevent width of the widget changing particularly useful when using
'text' and 'selectall' to do eg. in-place renaming.

Sample textbox content (# space, _ cursor).

Before:
    textbox before prompt: #term#
selectall prompt textbox : #_erm   <- shorter than other cases
      after pressing end : #term_

After:
    textbox before prompt: #term#
selectall prompt textbox : #_erm#
      after pressing end : #term_
