Replying to [comment:17 kini]:
> If they are mostly written as POSIX-compatible, why not just go all the
way and make them all call `sh` instead, and remove bashisms? But this is
getting off topic, I think...
Hmmm. In principle we should avoid bashisms whenever possible. (One of
the very few exceptions would IMHO be `set -o pipefail`, which is
supported by bashs >=3.0, but we still officially require just 2.04 since
this version is shipped with MacOS X 10.4 [which is a mess to support
anyway], <flame> and its users are incapable of installing a more recent
version </flame>.)
The main reason we use `bash` is that we can to some extent rely on it
being functional; there are too many broken Bourne shells, or at least
`/bin/sh`ells.

Nice service, thanks.
I just wonder how many parts of Sage (unconsciously exploiting it) break
if we fix this bug.
