It may not be a bad idea to read and understand reviews other people
are receiving for their microprojects, e.g. $gmane/243852.

"Change the type" is not technically incorrect per-se, but when
viewed in "git shortlog" output, it wastes more bytes than it
conveys information about this change if stated differently.  Any
patch that touch existing code is a "change" by definition.

Perhaps

	fsck.c:fsck_ident(): ident argument points at a const string

or something?

I see that the body of the patch follows the review by Peff on the
previous round of this series, so I'll forge a Helped-by: or
something into the log message when I queue this patch.

Thanks.
