Whoops. Consume the body of the first request
before making the subsequent /quit request.

Also: Simplified handling of selector expressions. As a result, complicated
multi-line expressions containing selectors and calls/indices with arguments
broken accross lines don't get indented the same way as before, but the change
is minimal (see tests) and there's no such code in the std library. It seems
a worthwhile compromise given the much simpler code.

Applied gofmt -w $GOROOT/src $GOROOT/misc .

Changeset 36c9c7810f14 broke support for grsec-patched kernels.
Those do not give back the address requested without MAP_FIXED,
so when verifying an mmap without this flag for success, the
resulting address must not be compared against the requested
address since it may have succeeded at a different location.

Apparently some distros don't let you ptrace attach
to your own existing processes.

Run strace on the child directly, instead, which
reportedly is more often allowed, and makes the
code simpler too.

- if a package path leads to subdirectories only,
  show command instead, if any
- to force documentation for a command, use the
  cmd/ prefix, as in: godoc cmd/go
  (note that for the go command, the prefix is
  not required since there is no actual go library
  package at the moment)
