[parisc-linux] Bug in more

[Richard Hirst]

Hi,
  I have found a bug in 'more', util-linux-2.10r source.
At startup tailequ() is called to match the last component of argv[0]
against "page".  tailequ() is broken because it accesses one location
below the start of argv[0].  This causes a crash on parisc, where the
stack grows upwards and argv[0] is the first element on the stack.
