Thanks, but -ECANNOTPARSE.  What are "inproperly merges"?

If I am reading the above correctly, blindly removing '*' from the
range will record a wrong merge in the result, because on the SVN
side only the history of part of the tree is merged but we represent
the result as a full merge (and Git only records full merge of
histories), no?

My gut feeling tells me that failing the import, saying "We cannot
represent this history", might be a more honest and safe thing to
do.
