Comment 7 for bug 841103

The unstable border_width problem was caused by the following lines being added to reparent() in commit 887024e2c6040eb5d3ec17b5906cf86bb6aaaa76 :
    xwc.border_width = 0;
    XConfigureWindow (dpy, id, CWBorderWidth, &xwc);

Removing those lines fixes several (but not all) border-related bugs
