On Linux and Mac I get the following error message when running `./mach help`.  I haven't had the time to investigate further.

~/Code/gecko/src % ./mach help                                                1
Error running mach:

    ['help']

The error occurred in mach itself. This is likely a bug in mach itself or a
fundamental problem with a loaded module.

Please consider filing a bug against mach by going to the URL:

    https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=mach


If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

AssertionError

This was caused by a shell expansion failing to evaluate.  Resolving.
