The compiler computes initialization order by finding
a spanning tree between a package's global variables.
But it does so by walking both variables and functions
and stops detecting cycles between variables when they
mix with a cycle of mutually recursive functions.

Before this fix, it was always an error to use the Close method on the
io.WriteCloser obtained from Cmd.StdinPipe, as it would race with the
Close performed by Cmd.Wait.

The method is simple: the parser just parses

        {{if A}}a{{else if B}}b{{end}}

to the same tree that would be produced by

        {{if A}}a{{else}}{{if B}}b{{end}}{{end}}

Thus no changes are required in text/template itself
or in html/template, only in text/template/parse.

The previous wording, though accurate, was hard to parse.
In particular, it was tempting to interpret "the method"
as referring to "the function f" instead of "Do", and
required effort to find the correct antecedent for
"this receiver".
