removal of "percent done" messages from git pull

I run a nightly script to build and test our product. I capture all the output and email it to interested parties. One very annoying thing is the "percent done" messages that come out of git pull. It results in log files that look like this:

+ git pull
remote: Generating pack...
remote: Done counting 204 objects.
Result has 107 objects.

I have found no way to make these messages go away.  When running in a 
"batch" mode, IMHO, interactive messages like these should not be emitted. 
  At least there should be a switch to suppress them.

Have I missed the magic switch that will accomplish this?

P.S. I'm using 1.4.4.1
