- [regress-extra] tested Tstat to ensure that a directory has size == 0 in the stat struct returned.
the reported length for directories must be zero
plan9' stat(3) says so...
add hexdump command to aid the debugging
Also skip the progression bar if hexdump is enabled.
kamid: always reply to auth with a struct kd_auth_proc
even when the authentication fails
fix walk_path error handling: do_clunk only when miss == 0
...otherwise nfid is not valid and do_clunk aborts.
add `edit' command
refactor the "write or create file" code into a function (woc_file) to share it with the `put' command.
