Subject: Fix show-trailing-whitespace in R2L text
X-Git-Tag: emacs-27.0.90~3427

Fix show-trailing-whitespace in R2L text

* src/xdisp.c (highlight_trailing_whitespace): Allow for
stretch glyphs at the left edge of R2L lines, when skipping
glyphs inserted by the display engine.  This unbreaks
show-trailing-whitespace in R2L lines.
