Make prompt_custom not print the segment if empty

Browse source 
Currently you can't make a conditional custom segment. This changes the
prompt_custom function responsible for printing custom segments so that
it won't print the segment in case the content is empty.

With this it becomes possible to make conditional custom prompts simply
by making it not print anything when it's not supposed to be shown.
