Author: pstef Date: Sun Jun 3 20:59:59 2018 New Revision: 334588 URL: https://svnweb.freebsd.org/changeset/base/334588 Log: indent(1): new option -lpl (always line up to parenthesis) With -lp, if a line has an opening paren which is not closed on that line, then continuation lines will be lined up to start at the character position just after the opening paren.
