Subject: 26.0.90; display-line-numbers-mode does not respect (line|wrap)-prefix
 '(space :align-to N) text property
Date: Mon, 16 Oct 2017 13:38:11 +1000

display-line-numbers-mode does not respect line-prefix or wrap-prefix text properties when set as '(space :align-to N).

To reproduce:

1. emacs -Q
3. type some text in *scratch* buffer
2. M-: (put-text-property (line-beginning-position) (line-end-position) 'line-prefix '(space :align-to 2))
3. M-x display-line-numbers-mode

Expected results:

Line numbers should be displayed before line-prefix (and/or wrap-prefix) space of 2 columns.

Actual results:

Line numbers eat the line-prefix and wrap-prefix space, effectively aligning the text back to 0.

Configuration:

GNU Emacs 26.0.90 (build 1, x86_64-apple-darwin17.0.0) of 2017-10-15
macOS 10.13 (17A405)
