There would be too many patches to clean this up for each file individually.

h3. I have split this up into 3 patches

Go from tabs to spaces without destroying alignment or indentation

Fix indentation to the correct number of spaces per level as specified by the style guide

Remove dangling whitespace at the end of lines

These should patch cleanly against commit @00d5139639afe9b206f2f68df95cebfeb28f28b1@

Once applied with @git apply@, @git diff -w@ should confirm that the changes are to whitespace only (with exceptions of files that had no newline on the last line, those were added too)

Previously, some of my changes made a @rake unit@ test fail, so I scaled back from modifying whitespace/indentation in multi-line strings.
