I don't know about svn specifically, but in the past it was typical
for programs requiring passwords and assuming interactive usage to
issue the password prompt to and read the password from /dev/tty,
rather than stdin/stdout. That allowed their use in a pipeline
without contaminating the pipe's data with the password prompt and
password. In "normal" usage /dev/tty and stdin/stdout/stderr are all
the same device, but when used via a library like subprocess, you
couldn't provide the password via stdin.
