fixed problem with doxygen wrapper

I fixed it in place (/afs/cern.ch/lhcb/software/releases/LBSCRIPTS/LBSCRIPTS_v8r7p1/InstallArea/scripts) because it was causing some annoying errors in Gaudi builds in the nightlies.

So that I remember what it does:

   ${parameter%%word}
          Remove matching suffix pattern.  The word is expanded to produce
          a pattern just as in pathname expansion.  If the pattern matches
          a trailing portion of the expanded value of parameter, then  the
          result  of the expansion is the expanded value of parameter with
          the shortest matching pattern (the ``%'' case)  or  the  longest
          matching  pattern  (the ``%%'' case) deleted.  If parameter is @
          or *, the pattern removal operation is  applied  to  each  posi‐
          tional  parameter  in  turn,  and the expansion is the resultant
          list.  If parameter is an array variable subscripted with  @  or
          *,  the  pattern  removal operation is applied to each member of
          the array in turn, and the expansion is the resultant list.
