since the semantics are unclear (bug#26624).
The vast majority of these are unused in-tree, and many of them
perform actions that aren't obvious when reading the code.

* lisp/emacs-lisp/macroexp.el (internal-macroexpand-for-load): Since
eager macro-expansion errors are no longer warnings, don't say so.
The position return by read-positioning-symbols is now the position in the
buffer, rather than the offset from the start of a form, enabling warning
positions in other parts of the buffer to be output.

OFFSET as a buffer position, not an offset from the start of a form.

a symbol with position.

position argument to each call of macroexp-warn-and-return.
This branch is intended to generate correct position information in warning
and error messages from the byte compiler, and is intended thereby to fix bugs
It introduces a new mechanism, the symbol with position. This is taken over
from the previous git branch scratch/accurate-warning-pos which was abandoned
for being too slow. The main difference in the current branch is that the
symbol `nil' is never given a position, thus speeding up NILP markedly.

Copyright-paperwork-exempt: yes
* lisp/emacs-lisp/cl-lib.el: Move all the generalized variable

since `setf' lives in gv.el (bug#49651).
As the Info node `(elisp) Specification List' explains, it is not

a `lambda' form. These should use `def-body' instead.

evaluation of the body altogether. I have no idea how to write it
correctly in this case.
This fixes bug#46573 which was introduced by commit
d79cf638f2.
The new code is a middle ground, which makes sure the instrumentation
point is used (so the coverage checker won't have ghost unreachable
instrumentation points) yet without artificially running the getter
when we only need to run the setter.
Instead of warning about unused vars during the analysis phase of
closure conversion, do it in the actual closure conversion by
annotating the code with "unused" warnings, so that the warnings
get emitted later by the bytecomp phase, like all other warnings,
at which point the line-number info is a bit less imprecise.
Take advantage of this change to wrap the expressions of unused
let-bound vars inside (ignore ...) so the byte-compiler can better
optimize them away.
Finally, promote `macroexp--warn-and-return` to "official" status
by removing its "--" marker.

Remove variable.

result is not used.

* test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el
(edebug-test-code-use-gv-expander): New test case.
It is necessary to make plist-get as a generalized variable, and this
definition allows user to use setf and other useful functions on
plist-get.
* lisp/emacs-lisp/gv.el: Add gv-define-expander for plist-get
* lisp/emacs-lisp/gv-tests.el: Add new tests for plist-get

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
