import: mention "stdin" (abbreviated) and add example
I actually didn't even think it was possible because I searched the
help text for "stdin", and didn't even think of searching for
"standard input". Let's mention the abbreviated form too to help
others like me. (When importing from stdin, we actually print a
message saying "applying patch from stdin".)
This patch also adds an example showing how to import from stdin.
