shifted margins, slight radius at end of lines, mark for new class for comment-header
input hover for textarea was colored, should have marked as submit, fixed
margins for comment .head
moved parent and permalink to header, with | separators
changed to spans that should have margins to improve the header
one concern: I removed , # as I didn' think the comma was needed, but the fact that this is some coding seemed odd too
I hope this and other rearranging doesn't mess up coding, and maybe there's code elsewhere about this comma that can/should be deleted
minor adjustment of h spacing
