Summary: Entity names in sgmlop

Initial Comment:
sgmlop handles entity names incorrectly in XML mode. 

According to
http://www.w3.org/TR/2000/REC-xml-20001006#sec-references
(Rule [68]):

EntityRef    ::=    '&' Name ';'

and

http://www.w3.org/TR/2000/REC-xml-20001006#NT-Name
(Rules [4], [5]):

Name ::= (Letter | '_' | ':') (NameChar)*
NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' |
CombiningChar | Extender 

So "-", "_" and ":" are allowed in entity names.

sgmlop currently uses (ISALNUM(*p) || *p == '.')
to test for legal characters inside entity names for
both modes (SGML and XML).

This patch adds "-", "_" and ":" to the set of allowed
characters (but only for XML mode).
