bug#18560: 24.4.50; vc commit truncates message to the first line

[Jarek Czekalski]

When I commit to svn using vc-next-action and provide a multiline
message, it gets truncated. Only the first line lands in the log.

I checked through variable vc-command-message, that the message
is passed through the -m switch, which seems a bit dirty for a multiline
message.

For me a serious bug - after months of work I lost a lot of log
messages.

This was already reported as part 2 in bug #1647: "vc-bzr commit bug on 
win32".
