graydon/rust — Issue #1394: Make rustc and rustdoc more user-friendly when no arguments are given

I think the current feedback, when rustc and rustdoc are called with no arguments can be improved:

$ rustc
error: No input filename given.
rust: upcall fail 'explicit failure', ../src/comp/driver/driver.rs:570
rust: domain main @0x10202aa00 root task failed

$ rustdoc
rust: upcall fail 'bounds check', ../src/rustdoc/rustdoc.rs:186
rust: domain main @0x10202aa00 root task failed

A "how to use" information instead of the "upcall fail" would be nice.
