[pypy-svn] r10037 - pypy/dist/pypy/documentation/revreport

New Revision: 10037

Modified:
   pypy/dist/pypy/documentation/revreport/revreport.py
Log:
revreport: should not make the symlink "current" point to the max revision
present, because this max revision's directory is likely to be still
half-empty and being generated.  If "latest != revdir" we should probably not
set the symlink at all and wait until the other process finishes and sets the
link itself.
