I've seen some problems when the Makefile commands didn't start at the first column. Maybe
it's solved with the more recenter make versions.

The Makefiles are generated files and don't need comments in the file, because the files
are not meant to be edited. This saves some bytes and the size of the deltas between
revisions is smaller.
