Would be nice to have also $omg_last_symbol to configure prompt end

[Reiner Keller]

Hello,

in my bash / with X11 + awesome font installed from Debian package and within remote putty access (also with Meslo font) I got both times a buggy prompt end. So it would be nice to get it configurable:

prompt+="${omg_last_symbol_color}${reset}\n"

Thanks ;)
