bug#40059: lisp-mode indentation not aligned vertically

[Spenser Truex]

This code sample demonstrates what I consider to be a bug in the
lisp-mode indentation.

Here is a very simple example:

(:a :b
 :c
    :d
 :e)


Here it is in an actual use case (defining Common Lisp packages)
(defpackage :example
  (:use :cl)

  ;; Here is the weird part:
  (:export :thing1
   :thing2
           :thing3
    :thing4
           :thing5))

A sane, non-buggy indentation would be this:
(defpackage :example
  (:use :cl)

  ;; These are aligned vertically:
  (:export :thing1
           :thing2
           :thing3
           :thing4
           :thing5))

This seems to be primarily caused by the keyword argument as the first
element of the unquoted list.

This is especially an issue if using aggressive formatting like
aggressive indent mode. <https://github.com/Malabarba/aggressive-indent-mode/issues/122>

I'm not able to reproduce this.  I tested on 27.0.90 and 26.3.  I get

(:a :b
    :c
    :d
    :e)

in both lisp-mode and emacs-lisp-mode.

Just to be clear, the process is such:

0. Open a buffer (eg. *scratch*) and M-x lisp-mode
1. Paste the sample into a buffer with the cursor at |
|(:a :b
    :c
    :d
    :e)
2. Run `indent-sexp'
3. Should look like this if reproduced successfully

(:a :b
 :c
    :d
 :e)

If that doesn't work, try placing the cursor on each line and run
`indent-for-tab-command'.

I had only tried indent-region before, but neither of these reproduce
for me either.

I don't think you've mentioned which Emacs versions you are seeing this
with.

Have you tried with emacs -Q?

More information was requested, but none was given within 6 weeks, so
I'm closing this bug.  It was already tagged unreproducible.

If this is still an issue, please reply to this email (use "Reply to
all" in your email client) and we can reopen the bug report.

Best regards,
