If I am trying to use some third-party stuff whose inner workings I
don't really fully understand and it doesn't work OOTB then I tend to
move on. All the more since the solution I outlined earlier is, though
by no means perfect*, "good enough" for my use case.

* vi-backward-blank-word simply stops after the first blank, so an
argument with blanks (ie a pathname) will not work with my quick fix. I
avoid blanks in file/pathnames like the plague so it's not much of a
problem for me but it's clearly not a general solution. And I do think
that a set of functions that works well with what the shell sees as a
single argument:

$>touch Test\ Directory
$>touch "Test Directory"

even if it contains funny characters would be nice to have. So maybe
I'll look into select-word-style, time permitting.
