Subject: [PATCH] Remove bashisms, replace with POSIX constructs

This replaces double conditional brackets with single ones and gets ris
of bashisms, so that the tool should be sourcable from any POSIX shell.

Constructs like [ $foo = "$bar"* ] yield filesystem-globbing behaviour
according to POSIX. A compliant way is to use case statements.
