I used the following perl script to search through my mail archive of
about 6 years, looking for header lines with any spaces between the
header name and the colon:

----------------------------------------------------------------------
#!/usr/bin/perl
 
$inheaders = 0;
while(<>)
{
  $mesgcount++ if /^From .*\d+:\d+:\d+/;
  $inheaders = 1 if /^From .*\d+:\d+:\d+/;
  $inheaders = 0 if /^\s*$/;
 
  $inheaders && /^[A-Za-z\-]+\s+:/ && print;
}
 
print "$mesgcount messages\n";
----------------------------------------------------------------------

The only output was: "73437 messages".  That confirms my suspicion,
since I don't remember ever seeing such a message.  I also ran the
script with some test data, where I purposely put in a space, and it
seemed to give the right results.
