FYI - cvs-import.sh changes

[Christian Iseli]

Hi folks,

It was noticed that the cvs-import script gets used by many folks, not
only for actually importing a new package into CVS, but also for
importing new versions of an existing package.

This latter usage led to a few cases where changes made in CVS got
silently lost when the updated package was imported.

After some discussions (like disallowing the use of cvs-import
for anything else than initial import) it was decided to modify the
script to at least show a diff of what's currently in CVS with what's
going to be imported (so that there is a chance the maintainer will
notice changes about to be undone), and will ask the maintainer to
enter a commit message.

Thanks to Jens Petersen for implementing the changes.

Cheers,
					C
