Starting from EAPI6, this is a built-in Portage functionality, maybe it was not included in Portage documentation earlier because it was epatch.eclass functionality which is exclusive for gentoo repo, but according with today's mandatory "eapply_user" it should be here.

+More-specific directories overrides less-specific, i.e. if more than one directory for the same package coexist, only patches from directory matches the first matching pattern will be applied. Patches for each package are applied in the POSIX lexicographic order. Patch file name must end in ".patch" or, for \fBEAPI\fR >= \fB6\fR, in ".diff".
+If package ebuild uses \fBEAPI\fR <= \fB5\fR, it must explicitly invoke \fBepatch_user\fR or inherit \fBepatch.eclass\fR(5) and rely on default \fBsrc_prepare\fR for apply patches. Otherwise, patches are silently ignored. If package ebuild uses \fBEAPI\fR >= \fB6\fR, applying user patches is mandatory.
