U+20F0 COMBINING ASTERISK ABOVE should be six-pointed in Noto Symbols and Noto Sans

[GoogleCodeExporter]

As a Latin and general purpose character, it's considered a math character, 
proposed in http://www.unicode.org/L2/L2007/07011-n3198-math.pdf.

It's not supposed to match the asterisk in the font, but should be always 
six-pointed.

(Side note: The character is unified with a Vedic star. In Indic fonts, the 
character could have different numbers of points, based on local Vedic 
traditions.)

Actually, in the PDF document that is linked in the original bug report the image of a 5 pointed asterisk is shown as representative of the character U+20F0. Also, as I look at the fonts on my computer outside of the Noto fonts there seems to be a fairly even split between 5 and 6 pointed asterisks. Finally, if we look at the Latex accentstar macro package documentation (http://cs.brown.edu/about/system/managed/latex/doc/accents.pdf) we can see that they too use the five pointed asterisk.

It seems as if there is no consensus on 5 versus 6 pointed asterisk for this use.
