Add a standard glyph name for hooked o instead of relying on .AM?

[Dorai Sitaram]

s.tmac defines a bunch of strings to display extra glyphs if the user calls the 
.AM macro. Most of these glyphs are already available with standard glyph 
names, and, as far as I can tell, the only new glyph defined is the hooked o, 
(equivalent to Latin small letter o with ogonek).  Both a string \*q and an 
escape sequence \[hooko] are defined. Is there any reason why the \[hooko] 
definition can't be moved outside of .AM, preferably with the more standard 
(RFC1354) name that looks like a winking pig, i.e.,  \(o;  ?  

(For comparison, .AM defines \*3, but the corresponding escape sequence \[yogh] 
is defined outside of .AM.)
