More stray http01 tokens

[tlhackque]

As noted in #693, stray tokens are left when ftp variants (ftpes, ftps) are used due to missing code.

Turns out, FTP_PORT is not honored when ftp is used. So stray FTP tokens can also be left behind.

Additionally, sftp and davfs also leave stray tokens, also due to missing code.

A bad side-effect of the missing code is that it falls thru to trying to delete something on the local file system.

(I'll have a PR with code later today.)
