adjust test-http output to non-default HGPORT, e.g. with run-tests.py -j

hgweb: clarify which address and port can/cannot be bound at startup (bug 769) The error message at startup when the address/port could not be bound was confusing: hg serve abort: cannot start server: Address already in use Be more explicit: $ hg serve -a localhost abort: cannot start server at 'localhost:8000': Address already in use Also be more explicit on success, showing hostname and ip address/port: $ hg -v serve -a localhost -p 80 listening at http://localhost/ (127.0.0.1:80) We are careful to handle a missconfigured machine whose hostname does not resolve, falling back to the address given at the command line. Remove a dead-code error message.

revlog: make sure the files are closed after an exception happens This prevents a corruption when the writes happen after the truncate initiated by the transaction rollback.

make sure not to reuse an existing append-file from a previous failed pull

Fix issue995 (copy --after and symlinks pointing to a directory) I haven't looked at other places that call os.path.isdir to make sure they're OK.
