Since d3e1ab0 kamiftp started to issue Twalks over ".". walk(9p) (from plan9ports) says that The name ``.'' (dot), meaning the current directory, is not used in the protocol. hinting that it shouldn't be used, and thus kamid rejects it. It's also redundant since it's always possible to do a walk to duplicate the directory fid instead of walkig "." which is what kamiftp now does.

don't use funopen(3) as it's not portable, found the hard way by cage. libbsd provides a funopen(3) on top of GNU libc' fopencookie, but I'd like to avoid dependencies on functions that are hard to port to other platforms.

This adds completions when building with readline. kamiftp now completes command name, special arguments (on/off), local paths (default readline behaviour) and remote paths. This also tells readline how to handle quotes and escape characters.

way more useful than a dumb strsep(" ")

it's useless as -C already implies it and -C must be use when connecting with TLS. To be definitely removed after 0.3.
