Bind F7 to an mkdir prompt 
This might have needed more thought, but we'll see.

Implement search iteration 
The interactive search now has its own keymap, overriding "input".

Closes #5

Enable pushing the search in a certain direction 
We want to make it possible to iterate all current matches.

Improve C-char parsing 
I was hoping that a superoptimiser would help me find a miraculous
branchless equation to cover it, but in the end the branching
doesn't hurt at all in our case.

It's more readable than `(((char >> 2) - 0x38) & 0x60) ^ char`
or `(char ^ 0x40) & (((char >> 1) ^ 0x20) | 0x5f)`.

sdn-install: explain why -dot is experimental 
Add an explanatory link, so that I don't need to look it up again.

sdn.1: take care about sentence spacing 
For more info, see e.g.
https://github.com/asciidoc/asciidoc-py3/issues/137

I'll probably commit to mandoc here but scdoc is appealing.

Somewhat sadly, it explicitly suppresses sentence spacing
but I'm wondering whether it couldn't be reimplemented better,
in a more AsciiDoc-like fashion.

Include a header required for kill()

Makefile: make portable, support static linking 
We can happily stick to POSIX and the usual variable names,
with the following exceptions:
 - pkg-config(1) is used to find libraries and compile flags
 - the new "static" target uses non-standard compiler
   and linker flags, though it's not the default target

sdn is predestined for wild distribution,
even the dynamically linked libc is rather suboptimal.

Cleanup 
The wchar_t variant of compute_width() is no longer needed.

So all in all the better help has saved code.

Bind M-Up to the "parent" action 
Taken from Windows Explorer, which previously used Backspace.

We might want to use h/l for parent/choose by default.

Not caring about C-d right now, we might have to convince the tty
to send it to us--I'm not sure if it does, or returns EOF.

Add an installation script 
Copying snippets from the README was uncomfortable and laborious,
and wasted a lot of space in the document, especially after
the recent additions.

Let the caller decide how to launch helpers 
In the end, we don't need to impose any policy on it,
and it removes a level of quoting, as well as an `eval`.

When resuming a child, resume the whole group 
SIGTSTP is sent to the entire foreground process group,
so do the some with our SIGCONT.

Debian's default sh (dash) doesn't replace itself with
the command, even if it's the last one in the -c option.

Of course, we do not need to use /bin/sh for the helpers
at all, though it doesn't cost us much.  We could also
issue an explicit `exec`.

README.adoc: add configuration for elvish 
And remove it from the "similar software" section.

Our relationship has progressed.

Other unusual shells I've checked before I gave up:
 - nushell lacks the ability to bind keys to user functions
 - yash can but is otherwise way too basic

Revisit zsh integration 
zsh's antisocial behaviour was fairly promptly fixed (thanks to
Stephane Chazelas and his patience).

zle-line-init and zle-line-reset seem to be user-defined widgets
and the order inverted.  Put zle-line-init before reset-prompt
because some people do weird things in there.

Make the outer prompt look more normal 
There's a slight issue with the inverted cell representing
the cursor standing out a bit too much amongst the rest of
the characters.

The resulting experience is a lot more consistent, though.
