bug#71106: dired-do-compress should check before attempting to read directories

$ tar tzvf plss00p020_nt00064.tar.gz
-rw-rw-rw- 0/0        24880644 2010-11-13 01:35 plss00p020.shp
-rw-rw-rw- 0/0        50551350 2010-11-13 01:35 plss00p020.dbf
-rw-rw-rw- 0/0          727452 2010-11-13 01:35 plss00p020.shx
-rw-rw-rw- 0/0           31363 2010-12-03 00:06 plss00p020.txt

Now in dired, use Z (runs the command dired-do-compress)

Compress or uncompress plss00p020_nt00064.tar.gz? (y or n) y

dired-insert-directory: Reading directory: No such file or directory, plss00p020_nt00064
emacs-version "29.3"

If it checked first to see if the directory it assumed was created was
really there, then it wouldn't have made an error.

Or it could be like unar, and make the directory, no matter what.

I cannot reproduce this.  I get: "Compress or uncompress: 1 file."
instead.

Did you miss some steps or some other important aspect of the recipe?

Please do the following (this time "guaranteed"!) experiment,
bash -ex <<"EOF"
cd /tmp
p=plss00p020 n=nt00064
touch $p.{shp,dbf,shx,txt}
tar -czf ${p}_${n}.tar.gz $p.*
tar tzvf ${p}_${n}.tar.gz
EOF
emacs -Q /tmp

Now hit spacebar until the cursor is upon plss00p020_nt00064.tar.gz
and hit Z then y .

Not only will you get the error message, the line showing plss00p020_nt00064.tar.gz
also has been temporarily abducted, and needs you to hit "g" to be seen again!

Thanks.  This is a duplicate of bug#47058, which was left unsolved.
So I have now solved it (I hope) on the master branch, and I'm closing
that bug and this one as well.
