[PATCH] sindex: avoid a warning with 'case -1:'

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

When parsing the format, there is a 'case -1:' which:
* seems to be there only for the following label (but mixing
  labels with cases, like here, is OK).
* on architectures where chars are unsigned, the compiler complains:
	warning: case label value is less than minimum value for type

So, remove the unneeded 'case -1:' and use an explicit 'default:'
to catch invalid formats. Also, align the label with the cases,
it looks nicer so.
