The functionality we use from compgen is not much, we can do the same
manually, with drastical improvements in speed, specially when dealing
with only a few rods.
This patch also has the sideffect that brekage reported by Jeroen Meijer
and SZEDER Gábor gets fixed because we no longer expand the resulting
words.
Other solutions with awk and sed are possible and more efficient when
dealing with tens of thousands of words. But is rarely the case. For the
common cases, this solution is faster.
