Subject: 1. buf fixed in eval_from_stream when first_statemente_only=true:
X-Git-Tag: 0.4.95@7852~656
X-Git-Url: http://matita.cs.unibo.it/gitweb/?a=commitdiff_plain;h=876455a152c9c4d6b1afcdfbee392210b2ec6b90;p=helm.git

1. buf fixed in eval_from_stream when first_statemente_only=true:
   the last computed states were lost
2. added a new watcher function to eval_from_stream.
   The function is called after the execution of each command.
