[PATCH] fix indent handling of range in case statements

[Jean-Christophe Dubois]

indent is not handling correctly case statements dealing with values range.

For example:

        case 0x01 ... 0x0b:

Will be transformed by indent in:

        case 0x01...0 x0b:

Which cannot compile.

This patch tries to fix this issue. I am not sure this is the correct 
solution but it seems to work for me.
