Committed patchset #1 manually as r211566.

Thanks for catching this Kent!
However, AFAICT my patch sets the permission correctly (checking locally and
looking at patch): the sed files are not executable.
So if the Linux bots are showing the wrong permission, they're not applying the
patch correctly.
How do we fix this? Force a full rebuild?

See for example:
build/sanitize-mac-build-log.sed

https://chromiumcodereview.appspot.com/download/issue19052002_2001_3001.diff
old mode 100755
new mode 100644

I don't know.  CQ might support no mode changes.
Clobber build won't help.

Thanks Kent,
I'll follow up with build people or on mailing list.
Not urgent, but should be fixed.

To followup (rather later):
CQ doesn't support changing executable bit, per this bug:
Commit queue doesn't change the svn:executable bit
https://code.google.com/p/chromium/issues/detail?id=162196

I've relanded by dcommit, and verified that the mode changed correctly,
so shouldn't cause any problems with check_perms this time.
