shellQuote
Quotes a string so that the shell (/bin/sh) will interpret the quoted string to mean @unquoted_string.
If you pass a filename to the shell, for example, you should first quote it with this function.
The return value must be freed with g_free().
The quoting style used is undefined (single or double quotes may be used).
