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.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.

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.

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.

Show external command line if appropriate
Since I'm already dealing with the fish shell.

All of our supported shells seem to handle cursor position
in Unicode (wide character) codepoints.

It was easiest and most straight-forward to pass the data
through yet-unused program arguments.

The cursor position is marked by a Unicode glyph equivalent
to ACS_DIAMOND, although ncurses doesn't get a chance
to make any ACS translation.

Set cursor to child when going to parent dir
That is, if it's missing from our history.

This makes for a more consistent experience when traversing
the filesystem.  Arguably, it's only good for when 'h' is
bound to the 'parent' action.

Also make sure that the offset and cursor are reset when
the path is changed.
