Track down a bug of empty `de XX' macros causing uncertain behaviour by

returning empty strings in roff_getstrn() instead of NULL.  This caused
maddeningly irregular segfaults in the pod2man preamble for `de IX'.
But only on DEC alpha.

Also integrate the kinda-probably-safe assertion relaxation in term.c,
field-tested by schwarze@.  This allows ALL [unpreprocessed] base and
xenocara manuals for all BSD systems to run without segfault.
