I guess it was such a trivial bug that no one cared to report. By the way,
wouldn't it be better if the same tilde expansion rules as with assignment
statements was applied to parameter expansions that assign default values?
assigns `/home/oguz:~otheruser' to `foo' regardless of whether `otheruser'
is a valid login name for an existing user. I don't see any reason why it
shouldn't assign `/home/oguz:/home/otheruser' instead. Yes, no one does
that yet and there's not much real world use case for this feature, but
this way it'd be more consistent with variable assignments, right?
