[gentoo-dev] epatch now searches for relative patches

[Mike Frysinger]

if you specify a patch to `epatch` which does not exist based on the name 
alone, epatch will now search for it in EPATCH_SOURCE.  this makes it useful 
to apply a set of patches which have a specific order but cannot use the 
existing lexicographical search.

quick example is a debian patchset that does not have names to imply sorting.  
instead, all the patches are ordered according to a file.  so now you can do:
	EPATCH_SOURCE=$WORKDIR/debian/patches epatch $(<series)
