Patch #393 - 2024/07/11

• add a check for ANSI SC/RC, to ignore CSI parameters.
• improve check for missing characters for bitmap-fonts by using the normal font for reference in the case where the current font, e.g., the wide-font was derived from the normal font and lacks per-character metrics (report by Rajeev V. Pillai).
• fix regression in error-recovery for SGR parameters from patch #357 (report by James Holderness).
• remove some duplicates in xtermcfg.h (report by Matthew Green).
• change default for --enable-imake configure option.
• fixes for wcwidth:
  • return 0 for format effectors, like a zero-width printing character rather than -1 like a control character (report by Rajeev V. Pillai).
  • correct doublewidth to account for reserved codepoints which are listed in the EastAsianWidth file.
  • add a special case for surrogate pairs, which might be checked in testing the wcwidth function.
• amend sixel bounds-check added in patch #371 to not wrap out-of-bounds data.
• eliminate maxStringParse limit for SIXEL.
• improve logic which ignores APC, PM and SOS controls to also not accumulate their data temporarily in a buffer.
• exclude TERM_INGRESS from cleanup of environment variables (patch by Iain Riley).
• fix some documentation typos (report by Thomas Wolff).
