The filetype needs to be set during BufRead in order for the did_filetype() check to prevent the file being detected as a conf file.  One example where this can occur is if a cgo file has a #include at the top of the file.  The # is detected in vim's generic configuration (conf file) toward the bottom of filetype.vim

That was the last build that was close to working.
I will try that change again next week.
Make is being very subtle today.

At the reverted-to CL, the ARM traceback appears
to be broken.  I'll look into that next week too.

- no empty lines inside empty structs and interfaces
- top-level declarations are separated by a blank line if
  a) they are of different kind (e.g. const vs type); or
  b) there are documentation comments associated with a
     declaration (this is new)
- applied gofmt -w misc src

The actual changes are in go/printer/nodes.go:397-400 (empty structs/interfaces),
and go/printer/printer.go:307-309 (extra line break). The remaining
changes are cleanups w/o changing the existing functionality.

Fixes issue  2570.

I am looking forward to not supporting two build

Collapse the arch,os-specific directories into the main directory
by renaming xxx/foo.c to foo_xxx.c, and so on.

There are no substantial edits here, except to the Makefile.
The assumption is that the Go tool will #define GOOS_darwin
and GOARCH_amd64 and will make any file named something
like signals_darwin.h available as signals_GOOS.h during the
build.  This replaces what used to be done with -I$(GOOS).

There is still work to be done to make runtime build with
standard tools, but this is a big step.  After this we will have
to write a script to generate all the generated files so they
can be checked in (instead of generated during the build).

Gotest tries to build things, for which it invokes make,
and it was too hard to coordinate go invoking gotest
invoking go to build the test binary, so put all the code
here instead.  Gotest will be deleted once we switch.

The only code that really made sense to copy verbatim
was the flag parsing.

This remains a work in progress.  There are still plenty
of things to clean up and make better, but this is a good
checkpoint.  It can run all the tests in the tree (except
runtime, which it can't build yet).

In 'go test' I deleted the leading package. prefix
from all the test names, since it contained no actual

This will still work with the current gotest too, since

Before/after, best of 3:
json.BenchmarkCodeEncoder  10  183495300 ns/op  10.58 MB/s
->
json.BenchmarkCodeEncoder  10  133025100 ns/op  14.59 MB/s

But don't get too excited about this.  These benchmarks, while
stable at any point of time, fluctuate wildly with any line of
code added or removed anywhere in the path due to stack splitting
issues.

It's currently much faster, though, and this is the API that
doesn't allocate so should always be faster in theory.
