All the first perens does is leave you sitting wherever you were before 
starting, whereas my example would have left you sitting in srcdir.
It makes no functional difference in the tar/untar job itself.

In truth, my example was from something I do all the time on SCO and is in 
sco's tar man page but it's such basic shell and tar usage that it works the 
same everywhere. I do it on Linux and FreeBSD too and I just verified on a 
5.3 box just to make sure instead of relying on memory and common sense.
