code review 4699041: go_tutorial: change the way it's generated.

go_tutorial: change the way it's generated.
No longer do we generate HTML from it; instead the input
file is already in HTML but has template invocations to
extract programs from other files.
Delete htmlgen, which is no longer needed.
Add tmpltohtml, which runs the templating code.

You haven't added tmpltohtml to the CL.

File doc/tmpltohtml.go (right):

http://codereview.appspot.com/4699041/diff/8001/doc/tmpltohtml.go#newcode48
doc/tmpltohtml.go:48: input := contents(name)
Just use ParseFile instead.

http://codereview.appspot.com/4699041/diff/8001/doc/tmpltohtml.go#newcode143
doc/tmpltohtml.go:143: if isInt2 {
This might be more readable as

if !isInt2 {
   line2 = match...
} else if line2 < line1 {
   log.Fatal...
}
