progress: Add estimated time remaining for long tasks
Output looks roughly like this:
updating [======================> ] 1547/4842 0m13s
output will either show h:m or m:s
progress: react more reasonably to nested progress topics
Previously, we'd reset the entire progress bar state when a topic was
completed, even if it wasn't the outermost progress topic. Now we
print the state of the next progress topic on the stack if one is left
rather than reset the progress bar.
eol: improve help on whether EOLs are changed in working copy or repository
Improved help to make it more clear for users which changes are only
changes in the working copy and which changes that will go into the
repository (on the following commit). Futhermore a note on when the
rules will be applied to the working directory.
