> MacOS... What does cat /dev/null | tar tf - give?
{{{
$ cat /dev/null | tar tf -

$ cat temp.pdf | tar jxf -

}}}
For the second example, the same thing happens with "tar xf" as with "tar
jxf". The man page for tar said nothing helpful about return codes. It
seems to be BSD tar, for what that's worth.
> Well, sage -i pkg1 pkg2 ... behaves the same ("Installing pkg1 pkg2
...", and did before), but I can add commas to both -- easily, until we
support (or use) spaces in spkg filenames...
I don't care that much about it. If you want to change it, that would be
fine, but don't worry about it too much.
> Agreed. I'd also remove long options with a single dash (i.e., only
allow -- there), but others disagreed a while ago.
I had a plan (at #21) to gradually phase them out, but that ticket has
stalled. There are also some issues with the approach there, and I'm not
planning on working on it any time soon.
