Thanks!

I tried renaming the element of the path from gentoo-source-6.18.29 to
'=gentoo-sources-6.18*' (enclosing in single quotes in the mv command
suffices), but it didn't work for me.

It also didn't work with '>=gentoo-sources-6.18.26'.

By "didn't work", I mean in directory
/var/db/repos/gentoo/sys-kernel/gentoo-sources, I typed in the command

    # ebuild gentoo-sources-6.18.29.ebuild clean prepare

, as documented in the /etc/portage/patches wiki page.  This operation
just ignored the "version" patch directory unless it was called
gentoo-sources-6.18.29 without any wildcards.

I even tried '\=gentoo-sources-6.18\*' in case it was insufficiently
quoted for the ebuild executable.  This didn't help either.

Have you any idea what I am doing/failing to do which prevents it working
for me?
