Another problem is the {foo,bar} construct. In bash `baz{foo,bar}'
expands to `bazfoo bazbar' while in ash it isn't expanded at all. A
few maintainer scripts use this construct, and I'll file some bugs
tonight if it hasn't been done already.
The packages I've found with this problem are dpkg and sgml-tools.
