Minor documentation fixes
|Reported by:||dghart||Owned by:||vadz|
1) In the wxRichTextCtrl docs there are a few instances where the 'brief' description is truncated at an 'i.e.'
2) There's truncation for a different reason in the Typedefs section of http://docs.wxwidgets.org/trunk/group__group__funcmacro__string.html. It seems that a '-' at the beginning of a line needs to be escaped before it's translated into a bullet.
3) There are places in http://docs.wxwidgets.org/trunk/classwx_cmd_line_parser.html where '--' appears as '–'. Apparently recent doxygen versions do this, perhaps intentionally. The first hyphen needs to be escaped.
patch.diff fixes these.
