Like "variable expansion" and "command substitution" in shell programming,
Kakoune expansions can expand to multiple "words" - that is, separate
arguments on the resulting command-line. However, unlike shell programming,
Kakoune expansions cannot _accidentally_ expand to multiple words, even if
the expansion contains whitespace or other special characters: only list types
can expand to multiple arguments. While in shell-programming it's good practice
to always wrap expansions in double-quotes, in Kakoune it's perfectly safe to
leave expansions unquoted.
Kakoune expansions cannot _accidentally_ expand to multiple words because they
contain whitespace or other special characters. Only expansions which
semantically contain a list of values (list-type options, registers, selections,
etc.) expand to multiple arguments. While in shell-programming it's good
practice to always wrap expansions in double-quotes, in Kakoune it's perfectly
safe to leave expansions unquoted.
