Shell Programming and Scripting

Hi All,
I am having hard time in getting two almost identical rows into one, I know how to do if starting word is unique, anyhow this is my problem

Input File:
issue1 5167
dum 1 1 kkk 7888
dum 2 1 ffff 7888
dum 2 2 llll 7888
dum 3 1 eee 7888
issue2 7667
dum 2 1 jjjj 8999
dum 2 2 jjjj 8999
dum 3 pppp 8999

Output should be:
issue1 5167 1 kkk 2 ffff 2 llll 3 eee
issue2 7667 2 jjjj 3 pppp


Can someone give me a idea, of how to proceed with this, would be grately helpful if anyone can put all those ideas into writing...

Thanks,
Ricky
