Update cli_commitRepoChanges.sh:
    
        - Previous to this commit: cli_commitRepoChanges builds a list of
          changes, verifies them, and later commits them up to central
          repository.  The working copy is not updated before commit, so
          if revision changes occur in central repository subversion says
          that you need to update your working copy first in order to
          commit changes from your working copy.
          
        - In this commit: the first action cli_commitRepoChanges does is
          to update the working copy. Later, a list of files is built
          using both `svn update' and `svn status' output.  With these
          outputs, cli_commitRepoChanges builds a common list of files
          that is used to print a report of revision changes.
    
        - Finally, if there are revision changes, cli_commitRepoChanges
          uses the list of changes (as previously defined by `svn status'
          output) to verify (through `svn diff' command) and later commit
          modifications up to central repository. Otherwise, if there is
          no change, there is nothing else for cli_commitRepoChanges to
          do.
