No man pages for apport-unpack and apport-retrace

Fixed in bzr head.

 apport (0.20) edgy; urgency=low
 .
   * apport: Renice ourself to priority 5 to not slow down the user's processes
     so heavily.
   * Add manpages for apport-retrace(1) and apport-unpack(1) and install them
     into apport. Closes: LP#58463
   * problem_report.py: Test attaching two files instead of one in the
     test_write_file() regression check to assert correct key sorting.
   * problem_report.py: Alter write() method to sort binary data to the end of
     the report. This makes reports easier to read, and also shows relevant
     information more quickly when progressively loading them in a web browser.
     Adapt regression tests accordingly.
   * Move setting of ExecutablePath from apport's InformationCollector ctor to
     apport_utils' report_add_proc_info(), where it belongs to. Check
     ExecutablePath in apport_utils' regression tests.
   * apport-unpack: Support '-' as report argument to read from stdin.
   * apport_utils.py, report_add_proc_info():
     - Apply some heuristics to determine whether the crashed process is an
       interpreted script (check if the Name in /proc/pid/status matches
       the second /proc/pid/cmdline part, and if that command line argument is
       an existing executable file). In the case of an interpreted script, set
       ExecutablePath to the script and InterpreterPath to the actually crashed
       ELF binary.
     - Test this with a shell (/bin/zgrep) and a Python (./apport-unpack)
       script in the test suite.
     - Closes: LP#58859
   * Add debian/apport.logrotate to add a daily 7-step /var/log/apport
     log rotation.
   * test-apport: Fix WCOREDUMP() and pidof checks in check_crash().
   * apport: Install a signal handler for all 'crashy' signals, which just logs
     the signal and stack info and exits. This should avoid a crashing apport
     examining itself, possibly in an endless loop. Closes: LP#58873
