"f77 -go" can destroy your source

[Shoe]

Unlike cc, f77 as distributed with 4.2BSD doesn't have a "-go" option
to produce symbol table info for sdb. Also, unlike cc, f77 accepts more
than one option character following a "-". Being unaware of either of
these sorry facts, I had someone type "f77 -go prog.f" and f77
cheerfully compiled an empty source file onto prog.f (with a brief
mention that _MAIN_ is undefined).

Sigh. Diffs to f77.c forthcoming if anyone wants them....
