Re: `printf %q` but more human readable

[Pier Paolo Grassi]

it depends on what the external executable does and how much slower is to
do the same task in bash, depending on this it may be quicker to execute an
external binary for certain tasks.
the parsing of a complex string and the application of special quoting
rules may be one of these tasks, the advantage of the external binary may
be subject of course to the length of the parsed string.
