Patch for Linux vacation(1), Version 0.11

The vacation programm had some problems with Exim as MTA. Exim does not wild
rewrite header lines like sendmail. So vacation had some problems recognizing
header lines with tab instead of space (RFC says any white space is okay). 
Also vacation did not generate correct 'From:' lines, some extra " become
necessary if realname contains brackets. This quick patch isn't perfect, 
actually it works well!
I did also add 'Precedence: list' to the code, no message is send if included 
in a header. Finally the man page has been updateted (shows also correct 
pathname now).

Quick description how to patch vacation(1) for Linux.
* Download the vacation tgz-archive and unpack it:
  tar -zxvf vacation-1.1.1.tar.gz
  If you wanna use a source rpm from a distribution, download it and do a:
  rpm -i vacation.spm 
  Then prepare it with:
  rpm -bp /usr/src/packages/SPECS/vacation.spec
* Go into the unpacked directory,
  when using an source rpm this is: /usr/src/packages/BUILD/vacation-1.1.1/
* Patch the source:
  patch < vacation-1.1.111.patch
* Make your new binaries now: 
  make all; make install
  Or when using an source rpm maybe this:
  make all; make -f Makefile.Linux install

If you don't like to patch (just do it!!!!), I did include a binary (i486)
and the new man page.

I hope I did nothing really stupid, this is my first patch.
Use at own risk, no warranty, as usual. Feedback is welcome! Maybe I'm 
lying on the beach or hunting dwarfs, but you will recieve a vacation 
message.... :)
