You are right about the imported part, but then, this change is a
trivial one when re-importing a new version.  On the other hand, it
significantly simplifies tasks like generating License Clearing
Reports and such.  If we would keep the full license headers for all
code imported from Linux or other projects we would rather give up
before even starting.

No, I think we should go on here and push this trhugh consequently,
setting a precedent for other projects, hoping they will adapt this
approach (and/or come up with even a better solution).  From the
feedback I've seen so far chances are not so bad.

Best regards,

Wolfgang Denk
