I would almost agree except for the help description of the -w option.
Also a : isn't a valid character for a name in Windows. Cygwin uses
some magic to represent it in UNICODE format though.

Consider the following as what should happen with "./a:b" but the
current result of "a:b" could already be considered correct. With the
following I think the output give fro "./a:b" is incorrect. Not
withstanding the argument for relational output of the windows path.
$ cygpath -w ../a:b | od -An -tx1c
43 3a 5c 6f 70 74 5c 63 79 67 77 69 6e 36 34 5c
C : \ o p t \ c y g w i n 6 4 \
68 6f 6d 65 5c 61 ef 80 ba 62 0a
h o m e \ a 357 200 272 b \n
