Emacs-28: Inadequate coding in hack-elisp-shorthands |

Hello, Emacs.
In emacs -Q in the emacs-28 branch, create the following two line file,
foobar.el, and try to load it:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(defvar foo-baz "foobar-baz")
FOOBARELISP-SHORTHANDS: (("foo" . "foobar")))
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
This will throw an error, but that isn't important.
What is important is that the symbol foobar-baz is created by the
elisp-shorthands facility.
This shouldn't happen since:
1/- There is no Local Variables section.
2/- There is no variable elisp-shorthands in that non-existent section.
The following errors are evident in hack-elisp-shorthands:
1/- The code doesn't check for a correctly formatted Local Variables
section.
2/- The code, even if it did check, would only check the last 3000 bytes
in the file. The section can occur anywhere in the last 3000
CHARACTERS.
3/- The code doesn't do a case-sensitive search for "elisp-shorthands".
4/- The code doesn't check for "elisp-shorthands" being a complete
symbol.
5/- The code doesn't even check that "elisp-shorthands" is in a comment.
I would suggest that these errors be corrected. I would also suggest
that the entire code and documentation for this new facility be
carefully reviewed by somebody who isn't the original author.

Also, if you want to converse, be polite. Your petty posturing doesn't
intimidate me. So go insult someone else.
