Why do -ffixed-line-length and -free... use - instead of =?

Will do.  A followup question: On IRC, Steve Kargl said that he'd prefer 
not to have a "-max-errors=none" synonym for "-max-errors=0" in the 
-max-errors patch that I submitted.  The -ffixed-line-length option has 
an identical interpretation: Setting the value to 0 eliminates the 
limits.  However, for this there is a "-ffixed-line-length-none" option.

Thus, should I leave out the "-ffixed-line-length=none" and equivalent 
"-ffree..." option in the patch to rearrange these?  It seems like it 
would be best to be consistent with these things.
