Hmm... the add_history(), or maybe it's rl_add_history(),
function seems to have been in ancient readline versions but at
some point all line history code was taken out to be its own
library.

Arch Linux drags in both readline.so and history.so in its
readline package. No one notices!
Trying import gnu.history; fails since there's no distinct
'history' package (yet) and Dub doesn't drag it in along with
readline.
D can call C and link to anything in /usr/lib easily. Done. It
works! How does D know to link to the libhistory.so library? I
didn't say "history" anywhere. But it works.
extern (C) {
void add_history(const char*);
}
I'm tempted to make a history package and submit it to DUB.
Maybe. After dinner...

Left/right arrows work, but up arrow still does not recall earlier commands. Maybe I need also a separate input history thing? If you start your program with rlwrap, for example `rlwrap cmd`, you'll get that for free.

stdin.readln line editing and recall with up arrow
stdin.readln() works fine until I, out of habit, use the up arrow to recall an earlier input and the left/right to move around and change a character. How do I get that to work?
