[Groff] grog misidentifies -ms document

[Robert Goulding]

If an -ms document contains a .SH heading and a table with a header 
(and hence a .TH request), grog identifies the document as -man rather 
than -ms.  For the following -ms document, grog guesses groff -man -t :

.SH
Price Table
.LP
The following table gives some prices:
.TS H
allbox, tab(&);
lb lb
l n.
Item&Price
.TH
Strawberries&$1.43
Apples&$1.00
.TE
