This function only handles quotes; if a string contains file globs,
arithmetic operators, variables, backticks, redirections, or other
special-to-the-shell features, the result will be different from the
result a real shell would produce (the variables, backticks, etc.
will be passed through literally instead of being expanded).
This function is guaranteed to succeed if applied to the result of
g_shell_quote(). If it fails, it returns null and sets the
error.
The quoted_string need not actually contain quoted or escaped text;
g_shell_unquote() simply goes through the string and unquotes/unescapes
anything that the shell would. Both single and double quotes are
handled, as are escapes including escaped newlines.
The return value must be freed with g_free().
Possible errors are in the G_SHELL_ERROR domain.
Shell quoting rules are a bit strange. Single quotes preserve the
literal string exactly. escape sequences are not allowed; not even
\' - if you want a ' in the quoted text, you have to do something
like 'foo'\''bar'. Double quotes allow $, ```, ", ``, and
newline to be escaped with backslash. Otherwise double quotes
preserve things literally.
Unquotes a string as the shell (/bin/sh) would.
