too-large src.zip file

[Jim McBeath <jimmc@xxxxxxxxxx>]

While working on building a release kit for my personal application
that uses Mckoi, I noticed that the src.zip file in Mckoi 0.93pr1 is 3MB
(3020001 bytes), but the unpacked source directory is only 3.6MB.  This
seemed like not enough compression, so I tried recreating a zip file from
the unpacked src directory, and it was only 826KB.  Unpacking the recreated
zip file creates the same source hierarchy as the original src.zip file,
so it's not truncated or otherwise missing any data.  And 826KB seems
like a more reasonable zip compression for 3.6MB than does a 3MB zip file.

Mckoi 0.92 exhibits a similar problem.  Why such a big src.zip file?
