Note that /cygdrive is Cygwin's default drive letter mount prefix but can be
changed.  Cygwin mount will show the prefixes in use (mount
--show-cygdrive-prefix), and Cygwin also comes with a handy cygpath utility
to convert between path types (cygpath -u c:).  These could be mentioned
along with /cygdrive in the notes.
