Antti Kupila 40e962e08e hclpack: fix marshalling file index positions
When marshalling, the current file index was not stored. Because of
this, a ';' was inserted multiple times for each file, even if the file
did not change.

When unmarshalling, the fileIdx determined by number of ';' was ignored.
Thus, if there were more than one file, all the positions would still
point to the first file.
