Ben Boeckel ff9145f8a5 executable: quote arguments ...

This allows command line arguments with spaces to be shown. The quoting
madness is because a single quote cannot appear within a single quoted
argument on the command line. To do so, you have to stop the single
quote argument, double quote the single quote, then open the single
quote again:

    $ echo 'before'"'"'after'
    before'after

Fixes #174
