dash(1) is kind of broken, I think by design/desire.
Herbert Xu forked a really old, and notably buggy at the time, NetBSD
/bin/sh to create dash back in mid 1997. Then for some reason he
stopped pulling in NetBSD changes and fixes early in 2002 and so dash
has diverged ever since, especially with its own unique changes.

Go up a couple of levels for even more good reading.
