some more tiny string fixes [patches]

[Benno Schulenberg]

Hi,

Attached the promised batch of other string fixes.

The sixth patch removes brackets around the MMDD... part on the 
second synopsis line of 'date'.  They are unneeded, because the 
first synopsis line already desscribes the possibility of having 
zero arguments or only an option argument.  Removing the brackets 
makes it clearer what "or set the system date" refers to.

The equal signs in the eighth patch (to 'dd') are just a suggestion.  
If not acceptable, then at least the "xM M" should move to the end 
of the line; it is rather confusing to find it there out of order.  
Maybe leave it out altogether?

In the thirteenth patch (to 'fmt'), maybe replace -DIGITS with 
-WIDTH, as in the Info document?  Or maybe deprecate the option, as 
it is for 'fold'?  Having one accept it and the other not seems odd.

Some of these synopsis changes may need to be made to the Info 
documents too, I haven't systematically checked that.

Benno
