+* Force `hg log` and `hg parents` to use the defaults style for output.
+ Otherwise, the parsing code fails to identify the tags. Also, reset the
+ 'default.log' value in case a user has an alias for `hg log` in his .hgrc.
+ (For example, some use log=-G to force the graph output). Thanks to
+ `dc <https://bitbucket.org/dc>`_ for the patch.
