Fix the indentation of the first line of preprocessor output

The -E output from clang did not produce the correct indentation on the first line.
This is because MoveToLine returned false, and when this happens,
the regular process for producing initial indentation is skipped.

Thanks to Eli for suggesting a way to simplify this to a one-line change.
