const std::string kUnescapedFileName

Satoru, it seems that we only declare char[] strings this way (for example,
const char kSymLinkToDevNull[] = "/dev/null";). The unit tests in
gdata_file_system_unittest.cc declare the std::string as local vars. I think it
would be better to conform to what the other code is doing?

kSomethingLike this is a naming convention used for constants. Here, the two
strings seem to be constants.

Done.

ditto
