Specs

dedent(text :: String.t()) :: String.t()

Removes as much common leading whitespace as possible from each line.

Each non-empty line has an equal amount of whitespace removed from its start.

Empty lines (containing only whitespace) are normalized to a single \n, with no other whitespace on the line.

Examples:

iex> Textwrap.dedent("    hello world")
"hello world"

iex> Textwrap.dedent("
...>  foo
...>    bar
...>  baz
...>      ")
"\nfoo\n  bar\nbaz\n"
