Looking at older *.c f= iles withing the FreeBSD repository which originated from 4.*BSD or UNIX shows s= ome legacy vcs-tags. These however mostly appear in the initial copyright state= ment and thus don't affect the code (or the manuals). [1] on the other hands states the following: "The dist tree can be cleaned up as necessary. Disabling keyword expansion = is recommended, as it makes no sense on unmodified vendor code and in some cas= es it can even be harmful. OpenSSH, for example, includes two files that origi= nated with FreeBSD and still contain the original version tags." One could of course get a snapshot (e.g. via svn) of some vendor import and= try to remove the tags using `svn propdel svn:keywords -R .`? I wouldn't vote for removing legacy tags in general, but would like to see sensable TH-statements within those manual pages I mentioned. Kind regards, Alexander 1: https://www.freebsd.org/doc/en_US.ISO8859-1/articles/committers-guide/ar= ticle.html#subversion-primer, Section 5.4.4.1.2.
