proposal: 'go get’ tool support http or ftp directly download source file.

[tomheng]

indeed, we only need a snapshot of source code, not all commit history of the code.

now ‘go get’ just support vcs(e.g. git), all them will pull a complete repo to local disk and then checkout a new

work copy of repo.

something i considered:

• burden of network downloading
• latest checkout work copy maybe not working(a expertise commit)

we can make ‘go get’ support directly download the source file(http or ftp) through go-import meta tag.

I don't see this proposal as compelling. There's no way to make the -u flag work as-is, and if we set about devising a means of making it work then we start to reinvent git. I'm going to close this as nobody else has shown interest since it was proposed.
