Unfortunately that doesn't work well enough- Even with POSIXLY_CORRECT=1 some bashisms work without any warning message. Yeah, so one kinda is left wondering what the point with POSIXLY_CORRECT is then.
I found this useful script: http://ftp.openbsd.org/ports/sysutils/checkbashisms/files/checkbashisms.pl . No doubt there might be other similar ones.
Another way is to actually develop a script using a #! line referring to some suitably limited shell on your platform, and then change that to /bin/sh before submitting as a patch or committing to git.
