I don't see in which way it makes a difference.
For the `helm-core` package, the info will be fetched from the headers
of `helm-core.el`.

The problem is not fundamental, but since the scripts we have generate
the `<pkg>-pkg.el` file in place, it means we end up with a dirty Git
clone where some of the tracked files have been locally modified, so
later operations like `merge` can get spurious conflicts.

The scripts try to handle those problems by cleaning after themselves,
but apparently not well enough because I've already had to go and
manually unwedge the system for a few packages that have their own
`<pkg>-pkg.el` file (`helm` and `helm-core` being among those I've had
to manually unwedge :-( ).

Since it works in place, there is no difference between "creating a new
*pkg.el file" and "modify the original *pkg.el files".
