time. This caused differences in the nanosecond portion of the time to
screwup the logic and made mtree think it should compare the modtime even
though "time" wasn't specified. The end result is that mtree couldn't deal
with procfs because procfs sets the mtime with high accuracy via microtime().
2. Clean up code so it compiles -Wall (except for sccsid's and copyright).
This included fixing several printf formats that where not correct,
and changing the data types of a few things.
3. Implement new option -i that produces indented mtree output files.
4. Implement new option -n that turns off directory comments.
5. Only emit /set records if something has changed since the last one.
