[Bug 1413978] [NEW] rename updates ctime. The glibc manual says otherwise.

[Jorge Morais]

Public bug reported:

glibc manual (both in the glibc included with Ubuntu 14.10 and also in
upstream glibc from git at 2014-01-23 ) at 14.9.9 File Times says:

"Renaming a file with 'rename' affects only the attribute change time
and modification time fields of the two parent directories involved, and
not the times for the file being renamed."

But in practice (tested on Ubuntu 14.10) renaming a file does change its
ctime.  I have checked it both at the command line and also with the
small program I will attach.
