Package: apt
Version: 0.8.15.10
Severity: normal
File: /usr/bin/apt-get

Dear Maintainer,

   * What led up to the situation?
Running `/usr/bin/apt-get -o quiet=1 dist-upgrade -y --no-download -q -u`

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Piping output to another command.  Enabling quiet from the command line.

   * What was the outcome of this action?
Getting the line: ^MExtracting templates from packages: 26%^MExtracting 
templates from packages: 52%^MExtracting templates from packages: 
78%^MExtracting templates from packages: 100%

   * What outcome did you expect instead?
An output without control characters, especially because the output is 
not a terminal.  Ideally, "Extracting templates from packages:" should 
not appear when piping the output and/or when using quiet settings.

Thanks,
Jayen
