tmux_prefix_highlight pushes right-aligned statusbar items

[parmort]

Hi, awesome theme (along with the compatibility with a bunch of programs)!

When I activate the prefix highlight, all the other right aligned statusbar items are pushed to the right 3 characters. With the copy highlight, the other items are moved 1 character.

This is all with the non-patched version.

My fix to at least avoid any shift with the prefix, was to add this line to my tmux config:

set -g @prefix_highlight_empty_prompt '    '

On my machine this was caused by a long hostname, so a more sensible solution is actually to increase the width of the right status bar similar to the proposed #27 .
