What I was thinking of doing was getting rid of the static variable
altogether: we should do what you say above, but in the form of a
state struct that's created and destroyed by additional calls from
dispell_init().  Then that state struct could also carry the
infrastructure for this additional hack.  It's a little more notation to
pass an additional parameter through all these routines, but from the
standpoint of understandability and maintainability it's clearly worth
it.

More like
NISpellState *NISpellInit();NISpellTerm(NISpellState *stat);

Because patches that reduce maintainability seldom get cleaned up after.
