[PATCH] _tmux: Use a colon to terminate options to _arguments itself

[Frank Terbeck <ft@xxxxxxxxxxxxxxxxxxx>]

In users/21384 it was reported that

  % tmux new-session -<tab>

...does not offer -A as a candidate for completion even though the
option is listed in the involved helper function _tmux-new-session().

-A is actually an option the _arguments function uses itself. The
documentation states:

    To avoid ambiguity, all options to _arguments itself may
    be separated from the spec forms by a single colon.

This commit changes each _arguments call to include the optional
colon, so problems like this are prevented now and hopefully in
the future.
