There is somehow no description of %c corename format specifier for
/proc/sys/kernel/core_pattern. The %c corename format specifier is
used by user-space application such as systemd-coredump, so it should
be documented.
To find where %c is handled in the kernel source code, look at
function format_corename() in fs/coredump.c.

Applied, thanks. A couple of notes:
- The patch was whitespace corrupted; I worked around that.
- There is no need to resend after five days; it can take me a little
while to catch up sometimes.
