Update to 316:

  Patch #316 - 2015/03/07

    revert change to make DCH honor top/bottom scrolling margins.
    For the record, both the VT420 and VT520 reference manuals
    incorrectly state that "DCH has no effect outside the scrolling
    margins."

    fix regression in DCH introduced in adjustment for limit-check
    in patch #315 (report/testcase by Zoltan Keri, also reported
    by Christian Weisgerber).

    correct default value for configure option --enable-initial-erase;
    it should be "False", but in patch #315 it was "Maybe", which
    differed from default set in patch #192.

  Patch #315 - 2015/03/02

    change default for --enable-narrowproto for Cygwin to "no" to
    better match contemporary configurations (report by Jens
    Schweikhardt, prompted by <a href=

    discussion).

    provide OSC 106 as an alternative to OSC 6, avoiding conflict
    with one of Terminal.app's undocumented escape sequences (report
    by Egmont Koblinger).

    fix an off-by-one in comparison when autowrap and left/right
    margins are combined (report by George Nachman).

    modify DECBI and DECFI to work outside the left/right margins,
    since the vague VT520 reference manual could support that
    interpretation (suggested by George Nachman).

    correct response for DECSCUSR in DECRQSS (report/analysis by
    George Nachman).

    add DECSLRM to list for DECRQSS in ctlseqs.ms (report by George
    Nachman).

    improve limit-checks versus assert's in the debugging version
    (reports by George Nachman).

    correct a problem with multiple writes to the right-margin when
    autowrap is turned off (report by George Nachman, also reported
    in Gnome #744819 by Ulf Magnusson).

    modify DCH to honor top/bottom and left/right margins (report
    by George Nachman).

    correct off-by-one in comparison so that DL honors left/right
    margins (report by George Nachman).

    correct logic of DECSCL, which always set 8-bit controls as a
    side-effect (report by George Nachman).

    correct loop limit for DECSED 1, when DECSCA is enabled (report
    by George Nachman).

    fix a entry in csi_table for "$", needed for CSI [ $ z (report
    by George Nachman).

    remove restriction from patch #279 changes on DECIC and DECDC
    to left-right mode (report by George Nachman).

    correct PID value returned in response to DECRQCRA (report/analysis
    by George Nachman).

    fix an ifdef'ing problem, where --disable-dec-locator would
    turn off logic needed for DECIC and DECDC (report by George
    Nachman).

    correct order of parameters in report for CSI 1 9 t, which
    gives the screensize in characters (report by George Nachman).

    add null pointer checks for a case in DECCRA where part of the
    target rectangle lies outside the screen limits (report by
    George Nachman).

    remove extra "6" for selective erase from DA1 response (report
    by George Nachman).

    support Xinerama screen specification in geometry parsing (patch
    by Nicolas George).

    add configure option --enable-initial-erase to set ptyInitialErase
    consistently with manpage, as well as adding a table in manpage
    to clarify the relationship between the resources related to
    the backarrow key (Debian #775952).

    add configure --enable-builtin-xpms to simplify compiling-in
    the icons introduced in <a href= "#xterm_284">patch #284
    (prompted by discussion with William Bulley).

    fix/improve autoconf macros:

	CF_WITH_APP_DEFAULTS, add paths for OSX

	CF_WITH_MAN2HTML, configure option "--with-man2html" provides
	"man2html" as alternative to groff's man/html conversion

    fix some minor issues in manpage (Jens Schweikhardt).
