Description dcb314 2018-05-11 09:08:30 UTC 
xorg-server-1.20.0/miext/rootless/rootlessGC.c:1238] -> [xorg-server-1.20.0/miext/rootless/rootlessGC.c:1246]: (warning) Identical inner 'if' condition is always true.

Source code is

    if (width > 0) {
        BoxRec box;

        /* ugh */
        box.x1 = dst->x + x + FONTMINBOUNDS(pGC->font, leftSideBearing);
        box.x2 = dst->x + x + FONTMAXBOUNDS(pGC->font, rightSideBearing);

        if (count > 1) {
            if (width > 0)
                box.x2 += width;
            else
                box.x1 += width;

box.x1 can never be incremented.
