works

this assumes that "z" is something, if you do "z=" then it breaks

na, you can never single quote a single quote, it is not possible. you have to
split the string on each single quote, assuming the string has any - then you
single quote the substrings as needed and escape the single delimiting quotes:

    $ echo "hello ' world"
    + echo 'hello '\'' world'

it gets more complicated with cygstart because an extra layer of
quoting/escaping is added - I about have a function to automate it - hopefully
will post soon
