Subject: 31.0.50; Can't install packages that require older Emacs
Date: Sat, 8 Mar 2025 07:29:17 -0300

With a prune init.el that only has these lines (so that it won't mess my 
real
custom-file):

(setq custom-file "~/.emacs.d/test-custom.el")
(when (file-exists-p (expand-file-name custom-file))
  (load custom-file))

Start emacs with "emacs" (note no emacs -Q)
M-x list-packages RET
Navigate to adjust-parens and hit RET
C-x o
TAB
RET, to action the Install button
y
Emacs says: package-compute-transaction: This package requires Emacs 
version 24.3

I select adjust-parens because it has a "Requires" tag.  I can install
it without problems if using the emacs-30 branch.

Looks like a mistake in the package name for the cond-star package.

Patch attached.

That's my bad, I didn't notice (or to be honest know about that header).
We should be able to just remove it.
