Path resolution is not picking the best option

[MisinformedDNA]

I have the following weights

Weight	Path
0.0	\blah\ABC\more\stuff\4.zip
53.0	c:\ABCfoo4

When I run z ABC 4, it always gives me the first one. This is true despite:

1. The first one has a weight of zero
2. There are fewer characters between ABC and 4 in the second one
3. ABC and 4 are in the same name in the second one
4. The first path isn't a directory

I am using v1.4.3.

I looked into the code and found that it chooses the first one because "4" is the prefix of the last path. This resolves issues 1-3, but issue 4 is still an issue. How does a zip file even make it into the DB?
