Replace space-based indents in prototypes with tabs

The previous commit removed the Vim modelines which replaced tabs with
spaces. This commit replaces the space-based indents with tabs.

Tabs are generally more compatible with various user preferences
regarding indentation of code. Using space-based indents is not flexible
regarding user preferences at all.
