Hello -

Text-properties seem to stop at a newline character in master rather
than the window's edge as they do in Emacs 26.3.

For example, if you use ledger-mode the following transaction:

2019-10-27 foo
    Expenses:Rent                           $ 10.00
    Assets:Checking

in Emacs 26.3 the face ledger-font-xact-highlight-face gets shown to the
window's right edge but in Emacs built from git master it is only shown
up through the newline character on each line. I've noticed this affects
magit too and likely others. I skimmed through the NEWS file but didn't
see anything about this; sorry if I've missed discussion elsewhere.

Thanks,
Alex

From NEWS:

  ** New face attribute ':extend' to control face extension at EOL.
  The new face attribute ':extend' controls whether to use the face for
  displaying the empty space beyond end of line (EOL) till the edge of
  the window.  By default, this attribute is non-nil only for 'region',
  'secondary-selection', 'hl-line' and diff faces; any other face that
  crosses end of line will not affect the display of the empty space at EOL.
