Well, b) is illegal, but not because there are dots in the comment.
Quoth son-of-1036:

From-content = address [ space "(" paren-phrase ")" ]
/ [ plain-phrase space ] "<" address ">"
paren-phrase = 1*( paren-char / space / encoded-word )
paren-char = <ASCII printable character except ()<>\>

So the only characters that are illegal in comments are "()<>\".
However, b) is illegal since the address can't have "<>". 

So, like, `gnus-extract-address-components' does handle these
correctly -- they are just broken.  :-)
