as:
,----[ C-h v fill-separate-heterogeneous-words-with-space RET ]
| fill-separate-heterogeneous-words-with-space is a variable defined in ‘fill.el’.
| Its value is t
| Original value was nil
| 
| Documentation:
| Non-nil means that use a space to separate words of different kind.
| This will be done with a word in the end of a line and a word in the
| beginning of the next line when concatenating them for filling those
| lines.  Whether to use a space is up to how the words are categorized.
| 
| You can customize this variable.
