config: oopsie, need to use strndup() on the pipe command 
Since it isn't NULL-terminated.

config: change syntax for pipe-command in key binding 
The pipe command can contain almost all printable characters. In
particular, we can expect it to contain '='.

Having the pipe command as part of the key breaks the key/value
splitting.

Change it so that it is instead an optional initial part of the value,
enclosed in '[]'.

I.e. instead of

    pipe-visible:cmd=binding

we now need to write

    pipe-visible=[cmd] binding

conf: bindings: allow several mappings for the same action

them as different actions.

spawn: add optional stdin/stdout/stderr redirection FDs

these FDs.

config: add support for appending a 'spawn' argument to key bindings 
A key binding may now have an optional ':<cmd>' string appended to the
key.

This is intended to be used like so:

  pipe-scrollback:sh -c "cat > file"=Print

TODO: we still only allow one *action*. Meaning you still cannot
specify multiple pipe-scrollback bindings, for example.

extract: extract_one() sets a fail flag that extract_finish() reads 
This allows us to safely call extract_finish() when extract_one()
failed, and we'll get the expected result; false, indicating
extract_finish() failed.

selection: don't skip SPACER cells in the generic foreach() 
As that breaks e.g. selection marking (SPACER cells didn't get
inverted when rendered).

Instead, skip them in extract_one() only. I.e. when copying text from
the grid.

instead of '0' to both padding cells (when character doesn't fit at
the end of the line), and to the cells following the actual character.

selection: recognize empty padding cells in a forced linewrap 
When printing a multi-column character at the end of the line, and it
doesn't fit, we currently insert a forced line-wrap. This means the
last character(s) on the previous line will be empty, followed by a
multi-column character in the first cell on the next line.

Without special code to handle this, the selection text extraction
code will insert a hard newline, since this is normally the correct
thing to do.

Add a TODO, to consider writing a special place holder value to these
padding cells.

term: print: also require width > 1 when checking if we need to force-wrap or not 
While this might seem like it would slow down things, it should in
fact help the compiler optimize: the "normal" code path, that prints
regular ASCII characters, always call term_print() with width == 1.
