nit: "AutofillDriverImpl instance" -> "an AutofillDriverImpl instance"

Done.

nit: Reduce the indentation of this line by two spaces.

[blundell, 2013/06/27 14:50:35]

4-space indenting is correct for a wrapped argument
(http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Functi...).
I moved all the other arguments to that same indentation per what the style
guide seems to indicate for this case.

Ah, I'd missed that this was also an argument to the AutofillDriverImpl
constructor.  In that case, I think you actually want to *increase* the
indentation by two spaces, as it should be four spaces from the 'A' in
'AutofillDriverImpl'.  Since this change has already landed, though, I wouldn't
worry about going back to fix this -- just something to keep in mind for the
future :)

(FWIW, I think most editors can be configured to apply these indentation rules
more or less automatically, which removes a lot of the tedium and guesswork in
making sure that things are aligned correctly.)

Deleting this call doesn't seem to have any effect. Is there anything I'm
mising?

[Ilya Sherman, 2013/06/26 22:36:18]

Not sure.  This might be meant to suppress some DCHECK or debug logging... but I
don't remember at this point.

[blundell, 2013/06/27 14:50:35]

Restored the line, as neither of us has a definitive argument that it's not
needed for some subtle reason.

Code inspection made me think that these calls were unnecessary here, and
indeed, removing them doesn't affect the tests. Is there anything I'm missing?

[Ilya Sherman, 2013/06/26 22:36:18]

These were probably needed when the test relied less on mocks, or the tested
code had a different memory model, or something like that.  I agree that it
looks like they are no longer needed.
