There are one to many lines with same file name but always same multiple
of files for all files.

Jim's solution works well:

#!/bin/sed -Ef
:a
N
s/(([^:\n]*)[^\n]*)\n\2(:.*)/\1\3/
ta
P
D

My own, that I found a few minutes after Jim,:

sedscript:
:eep;
N;
s|^([^:]*):([^\n]*)\n\1|\1:\2|;
teep;
P;D


What I don't understand:
The 3. line: s|^
Why is the ^ needed? Without it, the script hangs or loops forever.
