Request to support Cygwin in convert-standard-filename function

Hello,

I encounter a problem with `convert-standard-filename`,
https://www.gnu.org/software/emacs/manual/html_node/elisp/Standard-File-Names.html.
I call this function within a Cygwin environment, and this function could
not return me a MS-DOS/Windows format path. I think it treats Cygwin
environment as a normal *nix environment.

In Cygwin environment, the Emacs has a function called
`cygwin-convert-file-name-to-windows` which converts a expanded path to a
Windows path, e.g.:

    /cygdrive/c/Windows => c:\Windows

According to the description of the `convert-standard-filename`, it is
expected to be used only in places where the callee wants to convert a *nix
path to the underline OS path. I think it is appropriate we invoke the `
cygwin-convert-file-name-to-windows`  function inside the
`convert-standard-filename` function if it is called within a Cygwin
environment.

I am eager to hear your feedback.


Thanks,
David
