Quoting from the bash info documentation:
1. "Expansion is performed on the command line after it has been split
into `token's. There are seven kinds of expansion performed:"
2. "Each variable assignment is checked for unquoted tilde-prefixes
immediately following a `:' or `='. In these cases, tilde expansion is
also performed."
