This just affects how it's rendered; rather than attempting to highlight
these blocks as a shell script, they'll get highlighted as console
output.
See the rendered versions for a better comparison.
The extra whitespace was targeted at machine processing for a subset of
users for a subset of runs of CLIs. On the other hand, there is a lot
of concern over the extra verbose output.
A user can set the help template for man, if desired. They can even do
something (env? feature flag?) to make it only run when doing man
generation. We also have #3174 in the works.
So let's focus on the end-user reading `--help`. People wanting to use
`help2man` have workarounds to do what they need.
Fixes#3096
mitsuhiko immediately jumped into the examples and got tripped up by the
lack of documentation on feature flags needed.
I limited this to just the root ones because the rest are in a more
proper tutorial that steps through it all.
This creates distinct tutorial examples from complex feature examples
(more how-tos). Both sets are getting builder / derive versions (at
least the critical ones).
