well, it has to do with what one wants to set up with an option:

a=b,c=d,e= f,g = h

key=value with no space in between; spaces in between will be part of 
the key or value

of course i could be more liberal but it involves a bit more parsing; 
keep in mind that we had this key/value system right from the start 
(long ago) and then speed was more an issue than on todays machines
