o fix an *old* bug (since december 2002) making urpmf keeps parsed
    hdlist files in memory (was fixed for multitags, but not for simple tags)

(it may be a little stricter for urpmi since we exit(1) on parse_cmdline error)

  o exit with code 1 after displaying usage (instead of exit code 0)

(urpmi exit code "1" is correctly documented in urpmi's manpage)

  o fix -a and -o

  o display "usage" when no <pattern-expression> is given (#32658)

  o new option --wait-lock (#13025)

  o explicit error when using "urpmi ---install-src" as user with remote media
  o add support for "suggests": a newly suggested package is installed as if
    required, but one can remove it afterwards, or use --no-suggests
- urpmf
  o handle --suggests

all the work is done in perl-URPM 1.69
