Assuming a conventional setup, then
cygpath -m /
returns "c:/Cygwin". But if Cygwin is mounted at the root of a drive as in
mount "d:" "/"
OR
mount "d:/" "/"
then cygpath -m / returns "d:/". Note the trailing slash.
This is a terribly minor inconsistency and can easily be worked around (I
need to use the output of cygpath in an application) but (a) am I correct to
identify this mismatch in output as inconsistent and (b) would it be a pain
with many nasty consequences for loads of people if in some future
distribution it was made evident through a trailing slash that the output of
cygpath is always a directory? (So, in the particular example outlined,
here, you'd get "c:/Cygwin/").
