Yes, usually I do this too. However, as soon as you add "--unlink"
(which doesn't have a single-letter equivalent, and which is usually
required when unpacking a snapshot) to the set of options to GNU
tar, I think it will insist that you add a single hyphen in front of
the other options as well, and as explained, this introduces a new
requirement on the ordering of the options in this "bundle".
The man page for tar actually says
Note that you cannot mix bundled flags and --style flags; [...]
Though I'm not sure "-xpzvf" could be characterized as a "bundle"
Yes, I think it is sort of counter-intuitive that in the case of
"-xpzvf" order matters, while in "xpzvf" it doesn't.
