what's with all the seeming non-changes in the file?

[Mads Ager (google), 2013/02/25 07:00:17]

I'm afraid that was me. My editor strips out trailing whitespace. I'll disable
that since it seems that the rest of the team are more comfortable with trailing
white-spaces than I am. :-)

[Emily Fortuna, 2013/02/25 17:00:16]

No the issue is this file is auto-generated. So it shouldn't be saved/edited
manually in an editor.... were manual edits made to this file as well?
