cmd/doc: confusing error when a name does not exist #22810
Description
What version of Go are you using (go version)?
go version devel +da360f30e9 Sat Nov 18 06:31:57 2017 +0000 linux/amd64
Does this issue reproduce with the latest release?
No - this is fine on Go 1.9.2.
What did you do?
$ go doc bytes foo
doc: no such package: bytes
exit status 1
What did you expect to see?
The same that Go 1.9.2 gives:
$ go doc bytes foo
doc: no symbol foo in package bytes
exit status 1
Seems like a regression in 1.10 - will look into it myself.
