Do you want to only do this when the following line starts with a comma?

A little state machine might do (untested):

  h             # stash first line in hold space
  :again
  n             # get next line
  /^,/{         # starts with comma? do this stuff
    H           # append line to hold space
    x           # get hold space
    s/\n//      # remove embedded newline
    x           # put it back
    b again     # repeat for next line
  }
  x             # pull back hold space for printing

Put that in a file called "sedf" and try:

  sed -f sedf < olddata >newdata

and see how it goes. I think it will eat the last line as written.
