update docs bounty (11)

[ThomasWaldmann]

there are quite some docs issues: documentation

grab some doc update issues, create a PR against master (and, after discussion, also to 1.1-maint and 1.0-maint, if applicable, see here, also linked from PR submission template)

the bounty is for fixing 2 small issues or 1 bigger issue.
docs issues that already have a bounty on them do not qualify.
