Sometimes switching between branches can take more than a second or two, in which case `git checkout` would normally have shown a small progress meter to the user on the terminal to let them know that we are in fact working, and give them a reasonable idea of when we may finish. We now do obtain that progress meter from read-tree -v and include it in our main window's status bar. This allows users to see how many files we have checked out, how many remain, and what percentage of the operation is completed. It should help to keep users from getting bored during a large checkout operation. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
