Merge ~sylvain-pineau/plainbox-provider-checkbox:fix-oob-inline-comments into plainbox-provider-checkbox:master

[Sylvain Pineau]

Found while running the prototype of the snapped provider validation tool.

If a requires job field is made of just a comment, validation fails:

e.g:

requires:
  # a comment
