commit 9376f456af5824b0bda5b5dff62fc6f6cb1231bf
Author: Po Lu <luangruo@yahoo.com>
Commit: Po Lu <luangruo@yahoo.com>

    Fix display of text decorations in the mode line
    
    This is considered a temporary fix until the cause of
    fringe-overwriting underlines is established.
    
    * src/xterm.c (x_draw_glyph_string): Don't constrain decorations
    if the row is a tab or modeline.
