* Never use capital letters after `-`. Sentences start right after
the bullet and continue to the first period.
* When list elements are one or two sentences, use non-capitalized
format without terminators.
The two sentences are converted into one, separated by a semicolon.
This mainly applies to the cases with short sentences or when only
one of many list elements needs to have two sentences.
Example:
* `:opt_a` - basic description, no terminator
* `:opt_b` - also short description; this used to be second
sentence
* When at least one list element needs to have real sentences,
the whole list is formatted like that, with a period at the end
of each element:
* `:opt_a` - this is still short.
* `:opt_b` or `:opt_c` - but this is longer. May have multiple
sentences.
Or even paragraphs.
