A lot of the questions here have been about problems that would have been obvious (or at least more apparent) if the code had been consistently indented. Importantly, it's a lot easier to help someone who presents consistently-indented code.
I recently came across "Artistic Style" on SourceForge at http://astyle.sourceforge.net/ - and would like to suggest that its use might be beneficial.
The program can be configured to just about any imaginable coding style - I set up my configuration file as follows:
# astyle options
-A9
-c
-H
-k3
-t3
-W3
but you may prefer other settings. There are Linux, Mac, and Windows versions available - but I've tried only the Mac version.
Disclaimer: My only connection is that of a user; I don't think I know anyone associated with the project.
