* Doc/libfuncs.tex: don't use $math$ in description of pow(x,y,z);

	describe tuple()

	* Doc/libposixfile.tex: use tableiii instead of tableii, so
	partparse will work again (I know, chicken!)

	* Doc/libthread.tex: Added get_ident(); updated text on module
	availability

	* Doc/myformat.perl: Added sub do_cmd_Cpp
