When draw_phys_cursor_glyph (w, glyph_row, DRAW_CURSOR) happens, the background of a glyph is _not_ filled (i.e, !s->background_filled_p). This is presumably for a situation such as a FILLED_BOX_CURSOR so as not to erase the colored rectangle around the glyph. In the case of an HBAR_CURSOR; however, the result is a second imprint of the same glyph -- creating a bold appearance of the glyph with the cursor. Is the bold appearance "a feature", or is this something that has just been overlooked? Thanks, Keith
