Set up a Debian autobuilder with dash as a /bin/sh (apt-get install
dash, dpkg-reconfigure -plow dash and say 'yes'). You'll see those kind
of problems arise immediately.

Dash is a POSIX compatible shell, with almost no extension added (in
particular its echo has no -n option) which helps to find those kind of
issues.

It would help detecting git shell scripts that use bashism as well.
