This removes much of the complexity of the implementation and use of
the cmd/go/internal/cmdflag package, and makes the behavior of GOFLAGS
in 'go test' and 'go vet' more consistent with other subcommands.
Some of the complexity reduction has been offset by code comments and
bug fixes, particularly for the handling of GOPATH arguments and flag
terminators ('--').
Fixes #32471
Fixes #18682

<p><!-- https://golang.org/cl/211358 -->
|
|
Various flag parsing issues in <code>go</code> <code>test</code> and
|
|
<code>go</code> <code>vet</code> have been fixed. Notably, flags specified
|
|
in <code>GOFLAGS</code> are handled more consistently, and
|
|
the <code>-outputdir</code> flag now interprets relative paths relative to the
|
|
working directory of the <code>go</code> command (rather than the working
|
|
directory of each individual test).
