Patch #363 - 2020/12/26
-disable groff hyphenation in generated html when using man2html.
-change SCS “&4” Cyrillic to non-NRCS, per VT520 manual.
-amend fix for SCS in patch #198 to remove DEL rather than converting it to a
space (report by Thomas Wolff).
-modify state transitions for selecting character sets to eliminate an ambiguity
between the “A” used in VT220 versus VT320.
-improve error recovery when selecting characters by resetting to US ASCII when
no suitable encoding is found, e.g., attempting to use an NRCS sequence when
NRCS is not enabled.
-turn off hyphenation in “.txt” conversion, prompted by groff changes.
-add VT5xx ISO Latin-2 (prompted by discussion with Thomas Wolff).
-amend change from patch #361 to event-handling in CopyWait to handle

RGBA32 color format (patch by Leandro Lupori).
-modify the resource-parsing for disallowedPasteControls and similar lists of
names/numbers to recognize “~;” (tilde) for cancelling a given name/number.
-add ENQ, EOT and NUL to default for disallowedPasteControls.
-change default for disallowedPasteControls to omit the tab character
(suggested by Harald Dunkel).
-fix swapped height/width in regisScreenSize and maxGraphicSize resources using
"auto" value, from patch #314 (report by Anton Lavrentiev)
-revise patch #362 change for shift-modifier versus mouse protocol and
select/paste by adding resource shiftEscape, which can be enabled via a control
sequence (prompted by discussion with Matthijs van Duin).

run of xterm.
-add options -r and -t to vttests/query-color.pl to show the 6-digit RGB code
and actual colors.
