bug#37023: 27.0.50; Package.el error

[-- Attachment #1: Type: text/plain, Size: 8902 bytes --]

Attempting to install the package elisp-demos from MELPA results in the
error "package does not untar cleanly into directory". However

1. package installs fine with Emacs 26.2
2. Package tar file untars fine from the command line
3. M-x tar-untar-buffer works without error

The author has indicated the package contains an *.org file which is quite
large and includes Chinese characters, so this may be some sort of encoding
issue?

To reporoduce

1. Start emacs -Q
2. Add MELPA repository to package archives e.g.

(add-to-list 'package-archives `("melpa" . "https://melpa.org/packages/"))

3. M-x package-l;ist-packages
4. Try to install elisp-demos package

This is with current emacs 27.0.50 (commit
f4974d6fe6137f436763998be2). Tested under both Ubuntu 189.04 and current
ArchLinux systems.

Thanks.

I went down the rabbit hole (package.el->tar-mode.el->url-http.el) and
found that fixing bug#36773 exposed an unrelated 6-year old bug in
url-http.el.

Should be fixed now.

Fix tested and appears to be working. I believe the issue can be
closed/marked resolved.

thanks for the fast response.
