Description:
Substring Expansion actually works different than manpage states,
namely:
"If offset evaluates to a number less than zero, the value is used as
an offset from the end of the value of parameter."
Repeat-By:
x="abcdef"; echo "${x:-2}"
Expected: ef
Got: abcdef
or:
x="abcdef"; echo "${x:-2:1}"
Expected: e
Got: abcdef
