I can reproduce this behaviour, but is it really a bug?  Aren't the
names with '-' invalid?

The Bash Reference Manual says:

name

    A word consisting solely of letters, numbers, and underscores, and
    beginning with a letter or underscore. Names are used as shell
    variable and function names. Also referred to as an identifier.
