Remark: regarding sort order of SectionAll configuration settings

It looks like all these list should be sorted which imho is a good setup.
Currently four entries are not at sort order location.

• canonifyURLs
• enableRobotsTXT
• disableLanguages
• removePathAccents

if you want I could add another commit to align the sort (or create another PR or leave as is) just as you prefer.

Thanks. Please rebase and make the sort corrections you mentioned.

rebased, sorted, updated PR and set to Review

Thx for the review - I just took the stuff literally from the comandline help

just one suggestion:

What about using the phrase Whether to log WARNINGs when ... for the --print... flags

• Would match the description in fmt.warnf.
• imho makes using to the console superfluous

maybe without capitalizing warnings.

• printI18nWarnings (this actually is a warning not just additional output)
  (bool) Whether to log WARNINGs for each missing translation. Default is false.

• printPathWarnings
  (bool) Whether to log WARNINGs when Hugo publishes two or more files to the same path. Default is false.

• printUnusedTemplates
  (bool) Whether to log WARNINGs for each unused template. Default is false.

if you don't like that, I'll take your proposed changes for the four open ones as is

[jmooring]

What about using the phrase

Sure.

[jmooring]

At this point I really don't care. Let's just get it done.

hope that finally fits
