The previous tests assumed default locations for all commands, however they do not exist in the same place on all *nixes. I encountered this when the test was failing on MacOSX where it was expected hardcoded `/bin/sed` when in fact the code was identifying the correct local expansion of `/usr/bin/sed`. To make this test more robust, it now checks for the original location of all cmds and uses that in its expansion tests for `test_shell_command_wrapping()`.
