protoc option "--go_opt=paths=source_relative" not respected

[emicklei]

hi,

i am using libprotoc 3.17.1 with the following command to generate Go files:

protoc \
    -I . \
    -I ~/go/pkg/mod/github.com/envoyproxy/protoc-gen-validate@v0.6.1 \
    --go_out=. --go_opt=paths=source_relative \
    --go-grpc_out=. --go-grpc_opt=paths=source_relative \
    --validate_out="lang=go:clock" \
    clock/clock.proto

I expect the clock_grpc.pb.bo to appear in the clock directory but it is generated with the full go_package value as path in the directory clock

Hey! Add ,paths=source_relative to the validate_out flag and it'll put the file in the right place:

--validate_out="lang=go,paths=source_relative:clock"

thx, the paths=source_relative was mentioned in the docs but I tried --paths=source_relative as a flag on protoc. Your example will improve that doc.

but I tried --paths=source_relative as a flag on protoc

me,too. If you are ok, place check below.
