Archive-name: xmenu/patch1
Patch-To: xmenu: Volume 8, Issue 8

This patches some problems found by JQ Johnson <[e-mail]>,
who also offered the extensions.

Note that now, by default, the name of the menu item is printed.  To
have nothing printed simply use "item=".  Plus the "line" argument has
been changed to "-line".  Also xmenu now sets the exit status ala xmessage;
the menu items being numbered from 101.

  contains an equals sign then the string to the left of the equals is used as
  the displayed menu item and the the string to the right is used as the text
