} but not the second.  Maybe there's a better way that catches both.

Both bugs result from the alias expansion text merging with the following
text into a single longer token when the expanded input is re-parsed.

The patch I posted fixes this for the first bug by separating the expansion
into its own token, via an inserted space.

In the case of quote marks, this is not possible -- anything appended to
the quote (except a matching quote) becomes part of the quoted-string.

Therefore I think we really do need to figure out the deeper problem.  One
question is, why is the history reconstructed from the lexed token strings
instead of retaining the original input string?
