mdocml: If an eqn(7) starts on a new input line, be sure to output

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
If an eqn(7) starts on a new input line, be sure to output whitespace
in front of it.  Issue found by tedu@ in glOrtho(3).

There are also cases of excessive whitespace before and after
equations.  This patch neither fixes them nor makes them worse.
