Cosmetic console bug while installing packages

[bkraptor]

I am running this freshly-installed build on an Atom D2500:
2.1-BETA0 (amd64)
built on Sat Aug 25 13:20:22 EDT 2012
FreeBSD 8.3-RELEASE-p4

After restoring a backup of the config file and subsequent reboot, during package installation, I got the following display error in the console.

Notice the broken display of percentages and other messages on the bottom lines. This happened for all packages that were installed.

This happened when some tidy-ups were done to minimise the percentage progress output that would scroll across the console. Now it is putting a "\r" before the percentage is reported, thus going to the start of the line and scribbling over the first few chars of text.
I submitted a pull request to fix this up by being a bit smarter, leaving the percentage at the end of the line and using backspaces to rub out the old value before printing the next one.

This made it into the build:
2.1-BETA0 (i386)
built on Sun Aug 26 20:04:49 EDT 2012

I just updated my test system and got output on the console like:

Beginning package installation for blinkled . 100%
Installing blinkled and its dependencies. 100% 100% 100%

Note that the repeated 100% are because multiple files are downloaded. The details of every file name are not output to the console, so you see muliple sets of progress %age, one after the other.
