# unformat_parens.sh
#
# The manual pages before 2.10 treat format parentheses
# inconsistently. In some cases they are like
#
# .B name()
#
# while in others they are like:
#
# .BR name ()
#
# This script changes instances to the latter format.
# It does not fix all such instances: some will have to be
# done manually.
#
# Use the "-n" option for a dry run, in order to see what would be
# done, without actually doing it.
