Cycle between adding colon suffix and not in tab complete

Browse Source 
Allows completing a nick at the beginning of a message without a
colon by continuing to press tab, as well as after another nick
already followed by a colon without turning it into a comma-separated
list of nicks all followed by a colon. For example, tab can be used
to cycle between the following pairs:

    nick1: |
	nick1 |

	nick1, nick2: |
	nick1: nick2 |
