Good guess, buy why guess when you can look it up?

Stoned, times up. It was a trick question anyway -- you can't get all
the information out of NetBSD's anoncvs...

It looks like agc just changed all occurences of /usr/bin/tar to
TAR_FULLPATHNAME and tar to TAR_CMD in March, 1999. The full pathname
was actually introduced in create/perform.c with v1.26 in FreeBSD
land, by "jkh", with this commit message:

 Re-work make_dist() routine to build the tar command more reasonably.
 This should eliminate the problem with truncated packages.


This replaced a more devious and involved way of constructing the
command. It looks as if jkh just used a full path while he was in
there -- best current practice -- but no thought was ever given to
making sweeping changes to the other invocations of "tar", since they
weren't having any problems with them.
