Sorry, but this is unacceptable. You are adding a new level of
conditionals without changing indentation. Come on.
I understand and very much appreciate the desire to touch as few
lines of codes as possible, but that objective can not take
precedence over correct indentation, which is absolutely fundamental
for quality source code, which I guess we all want to work with.
A suggestion is to correctly use goto, in order to avoid changing a
very large block of code, if this makes sense. You might not need to
use goto, but might be able to use return instead. I haven't looked
into this function so I can't say for sure, but the above is in any
case not OK.

Same here about indentation. The added return line is also using
the wrong indentation character, please check your editor settings
and adjust it to the code style already used by the file. (I really
like the feature of some editors to autodetect the indent style used
in a file, but of course not all editors support this.)

Please avoid mixing whitespace changes with other changes. Send one
patch which fixes all whitespace issues at once.

Why are these {} added, and why have the variable when it isn't used?
