x-set-fingerprint sets empty fingerprint-value in subscription if there is an accidental line-break between E-Mail and Fingerprint
Expected Behavior
If the line with the command looks like this:
x-set-fingerprint mail@example.comThe command should return an error-message that no valid fingerprint was found.
Actual Behavior
The command empties the fingerprint field of the subscription and answers.
"Fingerprint for some_mail@mail.com set to ."
Steps to Reproduce the Problem
The line for the x-set-fingerprint-Command gets pretty long with the full length fingerprint.
Unfortunately some E-Mail-Clients force a line-break between the e-mail and the FP.
So the command in the request-mail looks like this:
x-set-fingerprint mail@example.com

Other information
I like paz idea from IRC:
12:49 <@paz> the functionality is wanted, one should be able to unset a fingerprint. But the described behaviour is not useful. We should maybe provide X-UNSET-FINGERPRINT, and protect X-SET-FINGERPRINT against (accidental) mis-use.
