Basics

language: "plaintext"

Long lines are split at whitespace and wrapped.

A long line.      ->      A long  ¦
        ¦                 line.   ¦

Short lines are concatenated and then wrapped as appropriate.

Three.        ¦      ->      Three. Short. ¦
Short.        ¦              Lines.        ¦
Lines.        ¦

Words that are longer than the wrapping width (like URLs) will be put on a new line but won't be broken up.

Go to www.example.com      ->      Go to    ¦
         ¦                         www.example.com

Paragraphs are separated by blank lines.

Foo bar baz.      ->      Foo bar  ¦
         ¦                baz.     ¦
Foo      ¦                         ¦
bar.     ¦                Foo bar. ¦

Or by a significant difference in indent (2 characters or more). This only applies to the default plain text type.

Foo bar baz.      ->      Foo bar   ¦
  Foo     ¦               baz.      ¦
  bar.    ¦                 Foo bar.¦

Also works with tab characters.

Two spaces at the end of a line will preserve the line break after it (this works anywhere).

Foo bar.··  ¦    ->      Foo bar.··  ¦
Baz foo     ¦            Baz foo bar ¦
bar baz.    ¦            baz.        ¦

Odd cases

Tab characters in the middle of a paragraph could cause improper wrapping.
