Log Message:
* src/preproc/grn/main.cc: Introduce BASE_THICKNESS, defining
line thicknesses to be integer multiples of this value.

* doc/groff.texinfo: Further checking/updating.


* src/preproc/grn/{main.cc, hgraph.cc}: Using point units to
specify line thickness instead of base units.  The new default
values are now 0.15,pt 0.45pt, and 0.75pt for thin, middle, and
thick lines respectively.

Removed unused variable `prevval'.

* src/preproc/grn/grn.man: Updated.
