[gcc, documentation, committed] Removed leading '-' from option index entries

[Daniel Franke <franke dot daniel at gmail dot com>]

http://gcc.gnu.org/onlinedocs/gcc/Option-Index.html

Above page states: 
"GCC's command line options are indexed here without any initial `-' or `--'."


2007-04-24  Daniel Franke  <franke.daniel@gmail.com>

       * doc/invoke.texi: Removed leading '-' from option index entries.


Tested info and html targets on i686-pc-linux-gnu.

Committed attached patches as obvious to 4.2 and mainline respectively.

Regards
	Daniel
