Fix hscroll of R2L lines that begin with a TAB or another wide glyph.

 src/xdisp.c (append_stretch_glyph): In a R2L glyph row, decrease the
 pixel width of the first glyph that is hscrolled from display.
 (display_line): In R2L glyph rows, don't give a negative offset to
 row->x when the first glyph begins before first_visible_x.
