Yes, but the bug was there as well.  It'll get merged into trunk in due time.

Thank you for confirming.

> Does mark matter in the minibuffer?

Yes.

forward-char is a low-level function which does not touch the mark.
forward-char-nomark OTOH is a command (only defined if you load
pc-select.el) which does affect the mark.  So `forward-char' is what we
want here.

It's a tradeoff: OT1H you don't see that the indentation changed, but
OTOH you do see that this part of the code has not been modified.
