py3: use class X: instead of class X(object):

The inheritance from object is implied in Python 3. So this should
be equivalent.

This change was generated via an automated search and replace. So there
may have been some accidental changes.

# genmerges is the workhorse of the test-merge-combination-*.t tests.

# Given:
# - a `range` function describing the possible values for file a
# - a `isgood` function to filter out uninteresting combination
# - a `createfile` function to actually write the values for file a on the
#   filesystem
#
# it print a series of lines that look like: abcd C: output of -T {files}
# describing the file a at respectively the base, p2, p1, merge
# revision. "C" indicates that hg merge had conflicts.
