Take menu's bwidth into account for position/size; reported by Thomas Adam.
The menu already limits entries with MENU_MAXENTRY, so don't bother
holding a command name limit as well.
Unlike free(3), XFree(3) can't be passed a NULL pointer.
No need to store screen colormap and visual; rather just use the X
macros in the one place they are needed.
Move redundant window attr fetch from maprequest directly into
client_init and perform that X roundtrip only once.
