ad09ce1d393c and replace ''' with """ to make some highlighting happy.
I have tried Debian's default emacs and the current CVS version. Default emacs
doesn't have highlighting enabled (and being emacs-illiterate I don't know how
to enable it) and the CVS emacs' Python highlighting has no problems with '
characters here.
dirstate.invalidate: avoid rebuilding _map
Since hasattr will call __getattr__, the call to hasattr(self, '_dirs')
will end up reparsing the dirstate file.
add dirstate._dirtypl variable
Theoretically, it's possible to forget modified dirstate
parents by doing:
dirstate.invalidate()
dirstate.setparents(p1, p2)
dirstate._map
The final access to _map should call _read(), which will
unconditionally overwrite dirstate._pl.
This doesn't actually happen right now because invalidate
accidentally ends up rebuilding dirstate._map.
