Corrected minor bug in mod_stepping.F

[arango]

Corrected a minor bug in mod_stepping.F that was triggered when ADJUST_BOUNDARY was not activated in the 4D-Var algorithms. We need to have instead:

#if defined ADJUST_BOUNDARY || defined ADJUST_STFLUX || \
    defined ADJUST_WSTRESS
      allocate ( Lfinp(Ngrids) )
      Lfinp(1:Ngrids)=1

      allocate ( Lfout(Ngrids) )
      Lfout(1:Ngrids)=1
#endif

We were initializing Lbout instead Lfout above. A compilation error resulted if ADJUST_BOUNDARY is not activated. Many thanks to Julia Levin for bringing this to my attention.

I also corrected several comments that include ' or " in a line. Some compilers issue warnings. This is actually a bug in the compiler. It should not check commented statement like:

!    H Q(k) = Q(k) T(k) + Gamma(k) q(k+1) e'(k)                        !

The above comment was changed to:

!    H Q(k) = Q(k) T(k) + Gamma(k) q(k+1) transpose[e(k)]              !
