Subject: Speed up troff.

* src/include/ptable.h (PTABLE): Make hash tables much more sparse
by changing `FULL_NUM' from 3 to 1.  This increases the allocated
memory by about 200kByte (which is nothing today) but assures that
there aren't extremely long searches for a free hash slot in case
that the hash function doesn't return a free one.  Due to the nature
of the entries in uniuni.cpp, the used hash function in ptable.cpp
is not optimal, but using a sparse array compensates this.
