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.
