How do I bind a variable for the minibuffer's use?

How do I bind a variable for the minibuffer's use?

[Alan Mackenzie]

Hello, Emacs.

How do I bind a variable for the minibuffer?  In particular, I want to
bind text-property-default-nonsticky to include '(separator . t).

The way it is done at the moment (in query-replace-read-from) is simply
to bind that variable, in the hope that that binding will be the one
seen by the minibuffer.  When the variable has a buffer local binding in
the current buffer, this doesn't work - the minibuffer only sees the
global binding.  This has led to bug #23127

Where is the function `current-minibuffer'?  With it, I could create a
local binding in the minibuffer.  Where is the functionality to bind the
default value of a variable?

Any other ideas?

(window-buffer (minibuffer-window))

There can be several minibuffers, so you need to be more precise.

When/where is this property added and then used?

I guess the simplest way would be to use minibuffer-with-setup-hook
where you setq-local those vars.

This has the downside that those buffer-local settings may leak to the
next use of the minibuffer, but it's probably harmless (and with any
luck minibuffer-inactive-mode will kill those buffer-local settings as
soon as you exit the minibuffer).
