Trying to stream clone when the server does not support it

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/F10" --stream

  streaming all changes

  remote: abort: server does not support narrow stream clones

  abort: pull failed on remote

Enable stream clone on the server

  $ echo "[experimental]" >> master/.hg/hgrc

  $ echo "server.stream-narrow-clones=True" >> master/.hg/hgrc

Cloning a specific file when stream clone is supported

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/F10" --stream
