The approach is a result of many trial-and-error
experiments but at this point reasonably simple
and open to arbitrary fine-tuning.
parser.go:
- Simplified handling of lead and line comments
(formerly called leading and trailing comments).
- Use a comments list instead of an array (I may
change this back - this is not obviously better
and uses more space).
doc.go:
- Remove comments from AST nodes that have been
'consumed' in the documentation to avoid duplicate
printing of them. Allows for better control of
what is printed w/o use of printing control flags
(which are hard to use and not fine-grained enough).

CONNECT has exactly the meaning
we want; most of the time people
connect to ip:port; we're connecting
to /_goRPC_
2. wait for a successful HTTP response
before assuming we are connected to
the RPC protocol. this allows better
error reporting and also keeps the

align the output args separately from the input args,
change cgo2c to insert the necessary padding
when the two arg lists are concatenated in the c
translation.
for example, there is a runtime
func indexstring(s string, i int32) (b byte)
right now in 6g those arguments are aligned in one
struct with s at offset 0, i at 16, and b at 20.
soon the b byte will be in its own struct and structs
are 8 aligned, so it will be b at 24.
right now cgo2c generates:
void indexstring(string s, int32 i, byte b)
this CL makes it generate, in --6g mode:
void indexstring(string s, int32 i, uint32, byte b)
this is valid 6c input, although not valid gcc input.
(the code is being generated for 6c only anyway.)
also, allow C code to be mixed in among the Go funcs.
