Resolve compiler warnings to comply with -Werror; tabs to spaces

[zyphlar]

When compiling under Ubuntu it fails because warnings about an unused int and unguarded (oddly-indented) else are treated as errors. This fixes that with a few curly braces and commented-out lines, and reduces future indent chaos by moving to spaces for indentation plus a bit of cleanup. (I don't care about spaces or tabs, but the source file was inconsistent/mixed)

Here's the git diff -w:
