Hi Duncan,

I tried using --non-interactive --trust-server-cert, but the call fails with error message,
svn: E175002: OPTIONS of 'https://127.0.0.1/svn/Repos': Server certificate verification failed: certificate issued for a different hostname, issuer is not trusted (https://127.0.0.1)

that's why I want to pass an input to accept the certificate (t)emporarily or (p)ermanently.
