'exclude' line in view- applies to all lines after

[xrouge]

The following lines won't generate a spec as intended:

views:
- src: -//depot/source_pathA/...
  targ: //import/target_pathA/...
- src: //depot/source_pathA/pathX/...
  targ: //import/target_pathA/pathX/...

will result in:

-//depot/source_pathA/...  //import/target_pathA/...
-//depot/source_pathA/pathX/... //import/target_pathA/pathX/...

pathA should be excluded, but pathX should be included. However the setting to '' before the for loop means that once an exclude line is encountered, all subsequent ones will be excluded:

        else:   # Ordinary workspace views which allow exclusions
            exclude = ''
            for v in self.options.views:
                lhs = v['src']
                if lhs[0] == '-':
                    exclude = '-'

The code should probably reset exclude to '' inside the loop:

        else:   # Ordinary workspace views which allow exclusions
            for v in self.options.views:
                lhs = v['src']
                if lhs[0] == '-':
                    exclude = '-'
                    lhs = lhs[1:]
                else:
                    exclude = ''
