I suppose this should be made to parse eventually, workaround meanwhile is to use a released version (like 2.0.0)

i.e. strip any trailing "-dev" string before feeding to semver

[afbjorklund]

Actually it was fine with the "-dev", it was the "\n" that was the problem here. Copied the code from docker, which uses --format.
