Description
Just released MC-4.8.26 is unable to enter tar.xz archives like the MC's own release tarball: "Cannot open tar archive mc_4.8.26.orig.tar.xz/uxz://".
MC-4.8.25 was able to do that successfully. tag.gz is OK, only tar.xz is affected as far as I can tell...

No I think it is a different issue.
For several years I have XZ_OPT environment variable set as follows:
XZ_OPT=-6v
Before 4.8.26 that was not causing any problems...
MC-4.8.26 can enter .tar.xz archives if started as follows:
XZ_OPT="" mc

Before 4.8.26:
$ file -L test.tar.xz test.tar.xz: xz compressed data
4.8.26:
$ file -L -z test.tar.xz test.tar.xz: POSIX tar archive (GNU) (xz compressed data)
Please update your ~/.config/mc/mc.ext.

Of course I did update my mc.ext, as advised, and could reproduce the problem still - that's why I've re-opened the issue.
XZ_OPT modifies output of the xz. I think MC is confused by "-v" part that prints extraction progress to STDERR. Formerly STDERR was captured, presented to user and I had to dismiss it with a brief keystroke, but it did not cause failure hence former behaviour was more robust.

That's weird, I can't remember any patches messing with stderr - probably need to blame.

that's some bizarre code. why not use dup2 properly right away?

is there a way to sensibly comment on the patches? i really don't feel like specifying the sha1, file, and line number for every issue i see ...
