I had forgotten about the $'foo\nbar\n' syntax. What is it
called again? I didn't see it in the 'Parameter Expansion'
section of the Posix standard. In fact I found:

2.6 Word Expansions
[...]
The '$' character is used to introduce parameter expansion,
command substitution, or arithmetic evaluation. If an
unquoted '$' is followed by a character that is either not
numeric, the name of one of the special parameters (see
Special Parameters), a valid first character of a variable
name, a left curly brace ( '{' ) or a left parenthesis, the
result is unspecified.

Which left me perplexed. Is that notation not standard?
