If an SSL client certificate is enabled (via http.sslcert or
GIT_SSL_CERT), prompt for the certificate password rather than
defaulting to OpenSSL's password prompt. This causes the prompt to only
appear once each run. Previously, OpenSSL prompted the user *many*
times, causing git to be unusable over HTTPS with client-side
certificates.
Note that the password is stored in memory in the clear while the
program is running. This may be a security problem if git crashes and
core dumps.
The user is always prompted, even if the certificate is not encrypted.
This should be fine; unencrypted certificates are rare and a security
risk anyway.
