I regularly used C-x C-f M-n C-SPC C-a C-w C-g to get the current
buffer's filename in the kill-ring (and the clipboard). This had two
issues:
1. It does not work with Ivy: C-a only moves back to the beginning of
the basename;
2. M-n runs the find-file-at-point machinery; if point is on a word
that looks like a domain (ends with ".com", ".net", …),
ffap *attempts to contact the domain*, which is inconvenient for a
bunch of reasons (locks up the editor, leaks data by sending it in
DNS requests, opens 9/tcp connections to random domains…)
The latter can be disabled by customizing ffap-machine-p-known; maybe
I'll go ahead and do that someday. In the meantime, defining a proper
function instead of relying on side-effects seems like a quick-win.
my/kill-ring-pipe-region allows me to quickly run pandoc on a Markdown
snippet and paste the resulting HTML in LWN's comment form. I'm sure
I will find other uses for it.

To prevent Emacs from modifying a user's init file behind their back,
the developers have decided that:
- by default, Emacs will call package-initialize before loading the
user's init file (thereby ensuring that out-of-the-box, when Emacs
starts, it activates packages installed in a previous session);
- the user can disable packages (among other things) using a new,
"early-init" file that will be read before package management
kicks in.
This has been committed to Emacs's master branch, so versions up to 26
still need to call package-initialize.
While in there, tuck package-archives in the Custom file. Hopefully
in a few years I can remove all this package cruft from my init file.

Also move them to .emacs.d. If some other program needs them, I guess
I'll make an ~/.icons folder or something.
Also break the 80-column rule 😨

Found with C-x 8 RET EDIT TAB. From the Unicode Standard[1]:
> Ancient Greek scribes generally wrote in continuous uppercase

Since With-Editor acts "as the $EDITOR of an external process", I like
the "change of speaker" idea.
For posterity, a cat-and-mouse game I just completed:
- notice the " Server" string in the minor mode list
- look for "Server" in M-x describe-mode: nothing
- find out about minor-mode-alist:
> (server-buffer-clients " Server")
> server-buffer-clients is a variable defined in ‘server.el’.
- visit ‘server.el’ link
- notice that I end up in /usr/local/share/emacs/25.1/lisp/
- assume that I am running Emacs master
- assume Emacs is dumb and gives priority to /usr/local/ over ~
- visit ~/Downloads/sources/emacs/lisp/server.el manually
- spend hours looking for " Server"
- find Changelog entries referencing Bug#20201
- see that this has been removed years ago
- check Emacs version
- well whadya know this actually is 25.1
- oh yeah this is my package-upgrade instance which runs 25.1 to make
sure packages are byte-compiled by the oldest Emacs on my system
- 🤦
So on the one hand, I spent the better part of this morning reading
trivia on incredibly obscure Greek symbols, and debugging Emacs
mode-line shenanigans. On the other hand, now I know that Astérix and
Obélix are named after Aristarchian symbols.

visual-line vs word-wrap:
AFAICT, visual-line is word-wrap plus some customizable options:
- fringe indicators;
- specialized editing commands.
So there is no reason to bother with word-wrap.
Appending through dir-locals:
I wanted to have lists in dir-locals *appended* to the variables,
rather than overwritten, eg:
;; in .emacs:
(setq my/foo '(1 2 3))
;; in .dir-locals.el:
((c-mode . ((my/foo . (4 5 6)))))
;; M-: my/foo in a C buffer:
(1 2 3 4 5 6)
I don't think there is built-in support for this. I guess the
simplest way to emulate it would be to
1. put (4 5 6) in some other variable my/bar;
2. write a hook that appends my/bar to my/foo.

C-M-S-h (ie control alt shift H) still works in graphical frames,
which covers 99% of my usage.

BECAUSE CONSISTENCY DAMMIT.

I mean I can't live with it on C-<backspace> or M-<backspace>.
