#8 Password from environment variable

[Christian]

Currently curlftpfs requires a commandline password
or a file .netrc to store the password for a session.

Both options are not perfect. A .netrc might stay on
the server and be visible later. A delete during the
session might (?) give problems with the session.

A password as option on the commandline might be visible
for others.

I would like to have a password read from the environment. e.g. export CURLFTPFSPASSWORD="secret"
- It's not visible with ps
- It disappears if curlftpfs is gone ( advantage against
.netrc )

Best regards,

Christian
