gitk: Fix switch statement in parseviewargs

In Tcl, a comment in a switch command where a pattern would be expected
doesn't do what one would expect, so this moves the comments inside the
actions.  Doing that shows up an extra "-" which this also removes.

With this, --merge is now handled properly.
