Saving worked, but did you log out everytime. Now it is checked if the
auth mechanism was actually changed before assuming the login is
invalid.

okay. I can't read. we already had a multiline config. It's the default.
So I reverted my change, except for making use of formText/cleanText for
proper line ending handling and I added made focused textareas a bit
larger.

Appending files now works at least for uncompressed tar files. Seeking
in compressed tars is not yet supported.

You can give a path and file contents in an array. However this didn't

unecessary reauthentication.
