So, I love cygwin, because it gives me powerful Unix command line tools for my Windows machine. Thank you. I love it. But: would it kill them to accept -? as a request for help?
$ diff -?
diff: invalid option -- ?
diff: Try `diff --help' for more information.
Why? What would be so terrible about understanding dash-query? I type it every time I want help, and have to look at that stupid error message every time. Grr...
