Clean up modelines and indentation.

To quote Icf0831717de10fc615971fa1cf75af2f1ea2d03d:

HT tab stops are set every 8 spaces on UN*X; UN*X tools that treat an HT
character as tabbing to 4-space tab stops, or that even are configurable
but *default* to 4-space tab stops (I'm looking at *you*, Xcode!) are
broken. tab-width: 4, tabstop=4, and tabSize=4 are errors if you ever
expect anybody to look at your file with a UN*X tool, and every text
file will probably be looked at by a UN*X tool at some point, so Don't
Do That.

Adjust indentation to reflect the mode lines.
