where to put `startx` serverargs

[Alexander Best]

hi there,

since i don't use ipv6 X produces the following warning when starting up:

_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/otaku:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

so i'd to start X this way: `startx -- -nolisten inet6`.

i looked through the man pages of startx and xinit but couldn't find where to
put the argument "-nolisten inet6" so `startx` picks it up automatically.

currently i have this extra line in /usr/local/bin/startx: "serverargs =
-nolisten inet6" but that's just a hack because i couldn't find any
information on where to put the serverarg.

cheers.
