    fix #49 - Occasional incorrect fontification of string literals due
    
    - the regex that marked backslashes in wysiwyg strings as punctuation
      was trying to only match wysiwyg strings that actually contained a
      backslash
    - this could lead to an off-by-one error matching the end of one
      wysiwyg string and the beginning of a suceeding wysiwyg string
      (see https://regex101.com/r/yqdATM/1/)
    - fixed by simply matching all wysiwyg strings and optionally marking
      contained backslashes as punctuation
