Behavior Difference Between unbundle and import --exact

[Kevin Christen]

I'm trying to test a workflow for a team who's members can't all pull from
the "gold copy" repository (don't ask...).  I've tried two different
approachs: sending the gold copy updates out as bundles, and sending them
out as patches to be imported with the --exact option.  The bundle approach
works fine, but the import approach fails when importing a merge changeset
with this message:

abort: cannot partially commit a merge (do not specify files or patterns)

The attached script demonstrates: run it as-is to see the failure, and
comment out line 2 ("export=1") to run it successfully using
bundle/unbundle.

I have two questions: what does the error message mean, and am I wrong to
expect that bundle/unbundle and export/import --exact work similarly?

This is with 1.0.1.

Thanks,
Kevin Christen
