[ For those reading this via bug-coreutils, the original bug report
is here: http://bugs.debian.org/339136. ]
Thanks for the report.
FYI, this change was mentioned in the NEWS for upstream coreutils-5.3.0,
10 months ago.
With stat, a specified format is no longer automatically newline terminated.
If you want a newline at the end of your output, append `\n' to the format
string.
One problem is that the NEWS entry is inaccurate,
since appending \n doesn't help at all.
Unfortunately, no one reported the problem before this.

You can work around that portably by using e.g.,
stat -L -c %s: / / | tr : '\n'
I expect to make stat accept \n, as NEWS says it does,
and to document that. Preliminary patch below.
I'm vacillating on whether to accept other backslash escapes.
