[patch/ob] Fix decimal point printing in printf

[Corinna Vinschen]

Hi,

I applied the below patch as obvious.  The latest change to _vfprintf_r
introduced a bug when printing integral float or double values.  A buggy
condition printed a decimal point, so that values as "1" were printed as
"1."  The below patch fixes that.

	* libc/stdio/vfprintf.c (_VFPRINTF_R): Drop printing a redundant
	decimal point in case the float argument is an integral value.
