v1.3

• Added beameroverlays option, which enables beamer overlays using the
  < and > characters.

• Added options breakindentnchars, breaksymbolsepleftnchars (alias
  breaksymbolsepnchars), breaksymbolseprightnchars,
  breaksymbolindentleftnchars (alias breaksymbolindentnchars), and
  breaksymbolindentrightnchars. These are identical to the pre-existing
  options without the nchars suffix, except that they allow indentation to
  be specified as an integer number of characters rather than as a dimension.
  As a result of these new options, \settowidth is no longer used in the
  preamble, resolving some font incompatibilities (#4).

• Clarified in the docs that breaksymbolsepright is a minimum, rather
  than exact, distance.
