progress: handle days, weeks and years
using hg clone svn://anonsvn.kde.org/home/kde/trunk kde ... with progress
yields 3008/1210830 1314h56m, which is unusable.
Add code to switch to days at 30 hours, to weeks at 15 days, and to years
at 55 weeks. A day has 24 hours, a week has 7 days, and a year has 52 weeks.
Months are intentionally omitted because they do not have a fixed length. The
Use of 52 weeks is a known and understandable estimate for a year.
It might make sense to spell our year to alert people when progress is
impractical, but...
