Re: weird \s

[Clarke Echols]

I've used troff since the 1980s, and I've NEVER used that form for 
defining point size.

Instead, I used .ps to establish the point size, then \s+nn where I've 
used values up to 15
or perhaps more -- don't recall for sure.

I then us \s0 to return to the original value before the change.

Same applies when I use \s-2 or \s-5, etc., then \s+n to get back to 
where I want
to be or some other value.
