doc/invoke.texi currently broken: here's a fix

["Ryan T. Sammartino" <ryants at shaw dot ca>]

Just did a cvs update and "make" bailed in gcc/invoke.texi with
"Mismatched {" errors.  Here is a fix.

  Enable (disable) generation of code using decrement and branch,
  DBcond(D), instructions.  This is enabled by default for the C4x.  To be
  on the safe side, this is disabled for the C3x, since the maximum
! iteration count on the C3x is @math{2^{23} + 1} (but who iterates loops more than
! @math{2^{23}} times on the C3x?).  Note that GCC will try to reverse a loop so
! that it can utilise the decrement and branch instruction, but will give
! up if there is more than one memory reference in the loop.  Thus a loop
! where the loop counter is decremented can generate slightly more
! efficient code, in cases where the RPTB instruction cannot be utilised.

  The maximum iteration count when using RPTS and RPTB (and DB on the C40)
! is @math{2^{31} + 1} since these instructions test if the iteration count is
! negative to terminate the loop.  If the iteration count is unsigned
! there is a possibility than the @math{2^{31} + 1} maximum iteration count may be
! exceeded.  This switch allows an unsigned iteration count.
