Suggest updating comment to mention display of certs in list as code is no longer just freeing each node

The certificate HEX data is printed differently than the data for previous certificates. Specifically, the previous HEX data was displayed in 16-byte rows. The way the certificate list data is currently displayed makes the output look inconsistent, and there might also be some utility to having 16-byte rows, as it's easier to visually parse to a specific location (?).
I'd suggest modifying the certificate list HEX data print logic to match that used for other HEX data. I realize that the [CERT %d] : text printed prior to each certificate will push the first 16-byte row out of alignment with with subsequent rows... I'd suggest adding a newline to the end of the "CERT" text so the first row of HEX data for each certificate starts at column zero.

Minor: there's an extra space between next and =.

A question: I don't see anything explicitly forbidding use of if without brackets in the coding standards (and I know you didn't create this code, just moved it)... There is an implicit mention of using "K&R" style and if as an example... Do we generally allow the "no-bracket" formatting for if statements? .. maybe only when there isn't an else statement?

Thanks for the great review! I added a commit to address the feedback. |

Add newline after cert number: [CERT %d] :\n... Current output (without new-line) looks like this:
HEX of Certificate LIST (DER format) :
[CERT 0] :308204AA30820392A003020102020900
B7B69033661B6B23300D06092A864886
Adding new-line would align HEX output (looks a little cleaner!)
