Moin!
hier sind die Umbrüche "verloren gegangen".
Offenbar geht es schief sobald man den Kram in eine Variable steckt.
Aber wieso, weshalb, warum?

Bash performs the expansion by executing command and replacing the com-
mand substitution with the standard output of the command, with any
trailing newlines deleted. Embedded newlines are not deleted, but they
may be removed during word splitting.
