Patch #337 - 2018/09/21

    regenerated configure script (report by Sven Joachim).
    revise/improve fix for scrolling in margins (report/analysis by Martin Hostettler):
    amend change to default-translations "select" subset to ensure that specific key-press actions are listed before generic key-press actions (reports by H Merijn Brand, Sven Joachim).

Patch #336 - 2018/09/19

    ensure that only one of PRIMARY and CLIPBOARD is owned by xterm at a given time (Debian #901249).
    documentation fixes (report by Lars Krueger):
        document SL and SR.
        document DECRPTUI, change number of digits to match VT420.
    revise omitTranslation resource, e.g., splitting “default” into several more useful categories.
    modify mask-logic to permit control- and meta- modifiers to be used in mouse protocol.
    several fixes for parsing/state (report/testcases by Martin Hostettler):
        remove an old/unimplemented entry for xterm-title from state table.
        save/restore wrap-flag when scrolling, to fix an inconsistency between jump-scrolling and normal-scrolling.
        improve a special case of wrapping where the cursor starts beyond the right-margin, and wraps at the terminal's last-column before the settable-margins can take effect.
        if origin mode is set, adjust a restored cursor column relative to the left margin.
        when scrolling a line within left/right margins, correct order of the fixups needed when a double-width character crosses the margin boundary.
    review/fix a few cases where the parsing state was not reset after completing a control sequence (prompted by report by Martin Hostettler).
    disallow XTCHECKSUM if the corresponding window-ops "SetChecksum" is unset.
    add print-vt-chars.pl script to illustrate the NRCS and codepages supported by xterm.
    add other-sgr.sh script to demonstrate the non-VT100 video attributes implemented in patch #305, and added a summary of their introduction in ECMA-48 to the control sequences document.
    add tabs and -tabs keywords to ttyModes resource to simplify workaround for terminal drivers which are not aware of UTF-8 (FreeBSD #229682).
    add VT5xx NRCS 7-bit Turkish and DEC Turkish.
    add VT5xx NRCS 7-bit Hebrew and DEC Hebrew.
    add VT5xx NRCS 7-bit Greek and DEC Greek.
    correct a few post-VT220 codepages to make them display without setting the NRCS state.
    extend vt100Graphics resource to include other character-sets such as the VT500 codepages in UTF-8 mode.
    add some VT5xx codepages to help with the discussion of 96-character sets: ISO Greek Supplemental, ISO Hebrew Supplemental, ISO Latin–5 Supplemental, and ISO Latin–Cyrillic.
    improve description of the VT300-controls for designating character sets, and fix a typo which indicated that some were used for 94-character sets (prompted by discussion with Lars Krueger).
    add private control XTCHECKSUM for modifying checksumExtension.
    factor out xterm's DECRQCRA checksum extensions as a resource setting checksumExtension.
    revise calculation of checksum for DECRQCRA to match DEC's terminals (using screenshots of vttest provided by Markus Schmidt).
    restore a fix for memory-checksum setup of DECCKSR from patch #315 incorrectly reverted in patch #334 as part of fix for DECRQCRA.
