I'm using Emacs 24.3.90.1 in Cygwin on Win7.
I have a Groovy script that reads from stdin, and it works fine when I run it from Bash, piping text into the process.
I'm now trying to select text in an Emacs buffer, and then execute "shell-command-on-region" The text I'm selecting appears to be identical to what I'm sending on the command line.
When I run this, it fails with "java.net.MalformedURLException: unknown protocol: c".
This obviously has something to do with my PATH, but I'm not sure what could be wrong. This might be more of a Cygwin question than an Emacs question. I tried going into my "*scratch*" buffer and printed out the PATH that the process sees, and it obviously has entries in "/c/..." (I set my cygdrive prefix to "c").

It doesn't sound like anything to do with the PATH. It sounds like
something is generating a Windows filename of the form c:/pathname, and
the script is treating that as a URL rather than a local filename. I
guess it has something to do with the way that Emacs implements piping
to a subprocess.
