• chompToIgnoreCase

  public String chompToIgnoreCase​(String seq)

Unbalanced openers and closers can be quoted (with ' or ") or escaped (with \). Those escapes will be left in the returned string, which is suitable for regexes (where we need to preserve the escape), but unsuitable for contains text strings; use unescape for that.
