[RFC PATCH 00/19] Diff machine: highlight moved lines.




For details on *why* see the commit message of the last commit.

The first five patches are slight refactorings to get into good
shape, the next patches are funneling all output through emit_line_*.

The second last patch introduces an option to buffer up all output
before printing, and then the last patch can color up moved lines
of code.

Any feedback welcome.

Thanks,
Stefan
