New version.

Patch 411 - 2026/08/24

• add a case for DECSWT in VT520 mode
• correct an index computation in VS15/VS16 logic for -emoji_width option
• add ich1 to terminfo where appropriate.
• drop “GTK_*” from environment filtering
• fix a couple of places in terminfo which used BEL rather than ST.
• add DECSCUSR 7 for the “power-up” configuration, which can be different from the documented VT520 behavior
• correct a limit-check added in patch 399, which resulted in regex-based selections to be limited to the first row of a wrapped line
• add resource brokenCopyArea, using that to control whether XCopyArea is used for indexing and scrolling, as well as inserting or deleting characters and lines.
• amend check for validity of C1 controls to check both whether wide-characters have been initialized, as well as whether the current encoding is UTF-8
• call Cleanup directly when processing SIGHUP, because the process running in xterm may ignore a killpg sent to the top-level screen's process
