[physfs] Physfs not seeing a file in zip archive

[Ivan Safrin]

You can find the file here:

https://dl.dropboxusercontent.com/u/4011871/test2.zip

And here's the testing code for it (it sees the first file, but not the
second while both are in the archive):

#include <stdio.h>
#include <physfs.h>

int main(int argc, char **argv) {

PHYSFS_init(NULL);
PHYSFS_addToSearchPath("test2.zip", 1);

if(PHYSFS_exists("src/engine/components/Health.lua")) {
printf("YES\n");
} else {
printf("NO\n");
}

if(PHYSFS_exists("src/engine/entities/PlayerChar.lua")) {
printf("YES\n");
} else {
printf("NO\n");
}
}
