Thanks for spotting this.  Actually, you've discovered two bugs.  The
first was that macros set with .blm were called on lines only
containing escape sequences which don't produce a node (\m, \f, etc.).
The second was that pic emitted `.sp -1' for such lines which is wrong
of course.

I've fixed it now in the CVS.  Please test.
