I'm trying to debug a vc problem with edebug and when stepping
through the source edebug prints the expression results.

VC code sometimes returns long lists with file names. In my
example one step returns a list of 1380 files and prints it to
the Message buffer as a single line which is quite long, so it
impacts scrolling.

Shouldn't the printing code be smarter and print long lists with
newlines, every item in a separate line, to avoid the long line
issue?
