$&

$& is used to split one long line over multiple lines for script readability.

$& 

Examples

echo -atg This is a really long line that, if there were complicated coding identifiers and variable names, $&
 would get really confusing and cramped without the added help of the $& identifier.

While this seems useless, if there was a heavy use of identifiers and such throughout the line, it would help make it much more readable.
