Avoid signaling "Beginning of buffer" in rust-lookng-back-macro
Also save some work if we don't have at least two characters behind us
in the buffer, we know we can't be looking at a macro then. The signal
occurs when one tries 'racer-describe' when positioned over "String",
which eventually ends up calling
(with-temp-buffer
(insert "<Target=str>")
(delay-mode-hooks (rust-mode))
(font-lock-ensure))
This simpler block will also trigger the error
(with-temp-buffer
(insert "<>")
(rust-mode)
(font-lock-ensure))
(font-lock-ensure) call ends up calling (rust-looking-back-macro).
