The following code:

  int closed;    /* valid iff peer != NULL */
  size_t len;    /* valid iff buf != NULL; 0 if peer == NULL */
  size_t offset; /* valid iff buf != NULL; 0 if len == 0 */

should be rewritten as:

  int closed;     // valid iff peer != NULL
  size_t len;     // valid iff buf != NULL; 0 if peer == NULL
  size_t offset;  // valid iff buf != NULL; 0 if len == 0

But the existing code lost the alignment when shifting the third comment
over to follow the two-space rule. Also warn about > 80 character lines
so they may be manually fixed up.

The following code was misconverted:

  BIO *peer; /* NULL if buf == NULL.
              * If peer != NULL, then peer->ptr is also a bio_bio_st,
              * and its "peer" member points back to us.
              * peer != NULL iff init != 0 in the BIO. */

Per the criteria in the comment, this comment is eligible, which is what
we want. Only continuation lines must be prefixed by spaces. But the
loop treated the first line as immediately ineligible. Moreover, in that
case, it dropped the line on the floor rather than echoing it. Fix this
by dropping that case.

Code like this:

    if (// Check if the cipher is supported for the current version.
        SSL_CIPHER_get_min_version(c) <= ssl3_protocol_version(ssl) &&

        sk_SSL_CIPHER_find(allow, &cipher_index, c)) {

should not get an extra space.

This is a utility to switch comments from /* C-style */ to // C++-style.
It's purely aesthetic, but it matches how most of Google C++ looks.
Running it over libssl, the script seems to get all but one or two cases
right.

We may also wish to convert the C code for consistency while we're here.
We've accidentally put both styles of comments all over the place, so
our toolchains can tolerate // in C.
