Ensure that files read in have a trailing new-line
In SCEP when retrieving the CA chain the certificates passed in
on the command-line (RA agent and CA cert) area printed along with
the contents of what was retrieved remotely.
If one of the filesystem certificates lacks a newline then the
output will be jumbled like:
-----END CERTIFICATE----------BEGIN CERTIFICATE-----\n
