+
+Same idea as (but implementation not directly based on) the Python shlex
+module. However, this implementation does not support any of the Python
+module's customization because it makes parsing slower and is fairly useless.
+You only get the default settings of shlex.split, which mimic the POSIX shell:
+http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html
+
+This implementation also deviates from the Python version in not treating \r
+specially, which I believe is more compliant.
+
+The algorithms in this crate are oblivious to UTF-8 high bytes, so they iterate
+over the bytes directly as a micro-optimization.
