It may be because sftp servers tend to translate ENOTDIR to  
SFTP_NO_SUCH_FILE.  (SFTP only has 4 real error codes.)  As I guess  
people are sick of hearing me say: We can't really depend on good  
error fidelity from transports, so we shouldn't put too much weight  
on fine-grained error codes.  I think HTTP can barely do better than  
"it succeeded" vs "it failed".
