currently, if abstract is set to unknown the abstract is set to an empty string. We can do better and let the auto-detect-abstract-from-pm-file routine run instead.
@monken Ideas on how we can do better?
Somehow https://github.com/CPAN-API/cpan-api/blob/master/lib/MetaCPAN/Script/Release.pm#L417 is not working correctly if the abstract is unknown.
Might be able to have a look at this today (Sunday).
Do we have an example of where this fails?
Nope, seems to be fixed: http://api.metacpan.org/v0/release/_search?q=abstract:unknown
