find-string-embedded

This searches, like find-string but unlike find-string it also searches through edits that are in media-snips in this edit.

• (send a-mred:searching-edit find-string-embedded str direction start end get-start? case-sensitive? pop-out?) -> two values: a media-edit and an integer
      str : string
      direction = 1 : int
      start = -1 : int
      end = -1 : int
      get-start? = #t : boolean
      case-sensitive? = #t : boolean
      pop-out? = #f : boolean

  Searches forr str, starting at start and ending at end. If direction is 1, then it searches forward, and if direction is -1, it searches backward.

  If varget-start? is #f,the end position of the string is returned. Otherwis, the start position of the string is returned.

  If pop-out? is #f and this edit is the edit in a wx:media-snip%, searching will not continue in the containing edit. Otherwise, searching will continue in the containing edit.
