With a document like the following, that contains a custom enumeration,
the preview generated by preview-latex for the math that is within the
[...] of the items, appears at the wrong position: After hitting C-c C-p
C-b, the document looks as follows

  \pcase[$\langtext{inc}$] h<begin embedded image>inc<end embedded
  image>ello

whereas of course I would expect

  \pcase[<begin embedded image>inc<end embedded image>] hello

Kind regards,
Ralf
