1d3ebaf302 Make sure the len() builtin always returns an answer. Previously, 
len(`') didn't return an answer.  Now it returns 0.

4ba4d3873a String operations could silently truncate long strings, leaving the output 
corrupted.  Mark's patch fixes this be removing the MAXTOK limitation on
substring operations and allowing the putback buffer size to be the limiting
factor.  If the putback buffer size if reached, m4 gives an error instead of
silently truncating the string.

4f377e65c4 Create temporary files in a secure directory, instead of using multiple 
filenames based on a single invocation of mktemp() in /tmp, which is
easily predictable after the first one.

pascal and vmstat.sparc.  All changed files on the vendor branch should

232eaee62a Make the $@ macro behave as described in the man page. 
This patch has been submitted by Andreas Burmester (i think) on the
German Usenet long ago.  Andreas told me that our m4 has quite more
subtle bugs, so we might consider using NGU m4 instead.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$ 
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.
