Looks good, just two minor points:

Unnecessary inline, see my previous mail for the explanation.

>+ } else

I usually add braces in this case: If braces are necessary for either
the if or the else-clause, then I add braces to both parts.

Could be applied as is, or I could write a patch with both changes.
Andrew - what do you prefer?
