Add test reproducing sf.net 2871216 issue.
(Space inserted when assigning parameters with negative item)
Remove unused if() since the "equal" case is handled in the following
switch. And add the "comma" test to switch.
Add another test to check the inverse. Adding spaces around
operators in params.
Wow, just changing the position of the "equal" case in the
switch made the test going green.
I'm not sure why, but it did the job so...
