Of course.  The value 1.0 is in the range from 0.1 to
10^5-1.  Therefore, the G6.5 edit descriptor is
equivalent to editing using

      F2.5,4(' ')

with a scale factor of zero.  The F edit descriptor
requires more than two characters, so it exceeds the
output field width of 2.  Therefore, two asterisks
are produced.  Thus, the output is "**    ", which
fits in the G edit descriptor's field width of six
characters.
