plass always did a `got add $file' before committing changes. However, this leads to a possibly misleading "file has unexpected status" error being printed to stderr. Instead, `got add $file' only when the file is new.

Now it always deletes the temporary file.

inline (with tweaks) writepass, it's redundant to have. While here also read/write blockwise instead that of linewise.

There's no real reason to have this variable, there's only one `got' usually and people are better off putting it somewhere in $PATH. Retain PLASS_GPG as there seem to be a little issue with gpg vs gpg2 so the knob may be useful in practice.

More often than not, services provide the URI for TOTP and not the raw secret. While it's easy to manually extract the secret from the querystring, teach totp how to do that on behalf of the user. Manpage bits will follow. Discussed with heph.

File::Temp lied. it says UNLINK defaults to true but the files were still in my /tmp. Quick workaround, needs something better that takes care also of cleaning up on die().
