svn commit: r285742 - head/usr.bin/last

[Ed Schouten]

New Revision: 285742
URL: https://svnweb.freebsd.org/changeset/base/285742

Log:
  Unbreak "last reboot".
  
  According to the last(1) man page, the "reboot" pseudo-user should print
  all system reboot entries. This got broken by the utmpx import, as
  records are typed.
  
  Re-add support for "last reboot" by specifically matching against
  SHUTDOWN_TIME and BOOT_TIME records.
