continuing from my previous email [1], here is an example of your command in
action:

    $ z=1
    $ cygstart bash -c \'echo $z\; read\'

and here is something that breaks your example:

    $ z=\'
    $ cygstart bash -c \'echo $z\; read\'

so you see, your command assumes that no single quotes will be between the
single quotes, which is just not robust. it seems something like one of these
will be needed:

- bash printf %q
- coreutils printf %q
- homebrew function [2]
