Hi @petervandenabeele, thanks for the patch!

+1 to merge

Hmmm, one of the Travis tests failed

• I presume this is a flickering test from the context of other PR tests passing around that time
• my patch is only a small documentation change

Will it be merged as is, or should I try to trigger a new Travis test by pushing an essentially empty commit in this PR ?

yes it's not related to your change (there are a bunch of unstable tests), it will be merged and you don't have to do anything.
