* For half and reverse line feeds, recognize SUSv2-style escape-digitschwarze2015-05-091-8/+20
| | | | | | | | | | | | sequences in the input stream in addition to traditional BSD-style escape-control-char sequences because traditional tools, for example Heirloom roff, produce SUSv2-style sequences. Switch the encoding of forward half line feeds in the output of -f back to SUSv2 style because that's likely to work with more tools than the non-standard traditional BSD-style sequence. Fully document these choices. Issues originally reported by bapt at FreeBSD. OK millert@ jmc@, and bapt@ also more or less agrees with the direction.

| | | | | | | | | | | | | this patch only changes two bits, note that '\011' != '9' == '\071'. Bug introduced by the original author, Michael Rendell, and committed by Keith Bostic on May 22, 1990 (CSRG SCCS rev. 5.1). The following operating systems are affected: 4.3BSD Reno, BSD Net/2, 4.4BSD, 4.4BSD Lite1, 4.4BSD Lite2, and all versions of 386BSD, NetBSD, OpenBSD, FreeBSD, DragonFly, Debian GNU/Linux (package bsdmainutils) and probably many others. "that's a fun one" millert@, "nice find" deraadt@
* 1) Fix a segfault triggered by an input line containing two consecutiveschwarze2014-10-161-17/+19
| | | | | | | | | | backspace characters beyond column MAX_SHRT, overflowing c_column. 2) Fix imcomplete initialization of the final element of the *count array by adding a missing pair of parentheses. 3) For code clarity and extra safety, change all variables dealing with column numbers from int to size_t such that they cannot overflow. Found while reviewing the patch from deraadt@'s reallocarray() rampage. Feedback and OK millert@.

* Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.millert2002-02-161-10/+10
