Bug#1691: X config allows invalid numeric range

[CD Rasmussen <cdr@sme.siemens.com>]

Package: x11/xbase
Version: 3.1.2-4

Problem Description:

   The X configuration will allow a user to put in a
   nonsensical string as a numeric range.

Expected behavior:

   The config program should do a check to ensure that numeric ranges
   are at least numeric ranges and within some reasonable set.  This
   would catch most of the typos.

Procedure to reproduce:

   Change the VertRefresh to 2--50 in the X config file.  This will
   introduce a syntax error that causes the X server to fail.

Thank you,
