no idea what this means

this does not follow the API naming convention ("unpack" comes first)

this doesn't work.  you normalized the input into a string.  just inline the

	local src
	for src ; do

the subshell should go away -- you don't even need it:
	[[ $? -eq 0 ]] || die ...

i wish we could merge with the file detection in unpack_makeself somehow
