Subject: [PATCH] (perl #131526) don't go beyond the end of the NUL in my_atof2

Perl_my_atof2() calls GROK_NUMERIC_RADIX() to detect and skip past
|
||||||
|
a decimal point and then can increment the parse pointer (s) before
|
||||||
|
checking what it points at, so skipping the terminating NUL if the
|
||||||
|
decimal point is immediately before the NUL.
