Fair enough.

Looks OK.  BTW, I saw that we could do

    included_els := $(shell tar -cvhf /dev/null --exclude-ignore=.elpaignore \
                                --exclude-vcs packages 2>&1 | grep '\.el$$')

except that --exclude-ignore is a fairly recent addition to GNU tar, so
it doesn't even work in Debian stable.
