Exactly.  The troff manual of Unix 7 is a shell script `tprint' as follows:

troff   $* m.mac m0
tbl m0a | troff   $* m.mac -
tbl m[1234] | troff   $* m.mac -
troff   $* m.mac m5
troff   $* m.mac table1
troff   $* m.mac table2
troff  $* m.mac add

To call this without changing its content would be simple with an 
environment variable GROFF_COMPAT:

GROFF_COMPAT=yes GROFF_TYPESETTER=html sh tprint
