-- subjunctive, imperative and participle), plus the imperfect indicative,
-- given up to four stems:
-- STEM = short pre-final stem (used for pres indic/imper 1s/2s/3s, required);
-- STEM2 = pre-vocalic stem (used for pres indic/imper 1p/2p,
--         impf indic 1s/2s/3s/3p, pres part) (required);
-- STEM3 = long pre-final stem (used for pres indic 3p and pres subj 1s/2s/3s/3p,
--         defaults to STEM);
-- STEM4 = pre-/j/ stem (used for 1p/2p of pres subj and impf indic,
--         defaults to STEM2).

-- The value of any of these stem arguments can actually consist of multiple
-- stems in a table or separated by a /; see add().
--
-- Note that this will not override an already-existing value for the
-- present participle, but will override all the rest.
