-/// Splits command line into separate arguments, in much the same way Unix shell
-/// would, but without many of expansion the shell would perform.
-///
-/// The split functionality is compatible with behaviour of Unix shell, but with
-/// word expansions limited to quote removal, and without special token
-/// recognition rules for operators.
-///
-/// The result is exactly the same as one obtained from Unix shell as long as
-/// those unsupported features are not present in input: no operators, no
-/// variable assignments, no tilde expansion, no parameter expansion, no command
-/// substitution, no arithmetic expansion, no pathname expansion.
-///
-/// In case those unsupported shell features are present, the syntax that
-/// introduce them is interpreted literally.
-///
-/// # Errors
-///
-/// When input contains unmatched quote, an error is returned.
-///
-/// # Compatibility with other implementations
-///
-/// It should be fully compatible with g_shell_parse_argv from GLib, except that
-/// in GLib it is an error not to have any words after tokenization.
-///
-/// It is also very close to shlex.split available in Python standard library,
-/// when used in POSIX mode with support for comments. Though, shlex
-/// implementation diverges from POSIX, and from implementation contained herein
-/// in three aspects. First, it doesn't support line continuations.
-/// Second, inside double quotes, the backslash characters retains its special
-/// meaning as an escape character only when followed by \\ or \", whereas POSIX
-/// specifies that it should retain its special meaning when followed by: $, \`,
-/// \", \\, or a newline. Third, it treats carriage return as one of delimiters.
-///
-/// # Examples
-///
-/// Building an executable using compiler obtained from CC environment variable
-/// and compiler flags from both CFLAGS and CPPFLAGS. Similar to default build
-/// rule for C used in GNU Make:
-///
-/// ```rust,no_run
-/// use std::env::var;
-/// use std::process::Command;
-///
-/// let cc = var("CC").unwrap_or_else(|_| "cc".to_owned());
-///
-/// let cflags_str = var("CFLAGS").unwrap_or_else(|_| String::new());
-/// let cflags = shell_words::split(&cflags_str).expect("failed to parse CFLAGS");
-///
-/// let cppflags_str = var("CPPFLAGS").unwrap_or_else(|_| String::new());
-/// let cppflags = shell_words::split(&cppflags_str).expect("failed to parse CPPFLAGS");
-///
-/// Command::new(cc)
-///     .args(cflags)
-///     .args(cppflags)
-///     .args(&["-c", "a.c", "-o", "a.out"])
-///     .spawn()
-///     .expect("failed to start subprocess")
