Issue 3182: ref-update only shows outputs at the end
Status:  New
Owner: ----
Reported by wer...@beroux.com, Feb 17, 2015
Affected Version: 2.10

What steps will reproduce the problem?
1. Create a hooks/ref-update script that takes some time and outputs as it goes (e.g., doing a build)

What is the expected output? What do you see instead?
Expecting to see the outputs progressively as they come (like gcloud does during a git push).

Actually only shows the outputs once the script finished (even if the script contains I/O flush statements.

Note: It's a Python script calling:

   print '....'
   sys.stdout.flush()

Tried also with stderr with same results.
