What appears to be happening here is that because there's no end of word
character after the expanded "{" we run straight onto the "bar" and only
call ihwend() via hwend() after that.  As alias expansion is tied to
word-handling, we only then look at the test that resets the position in
the history line, which is too late.

I'm not sure how to fix this.  Ideally, I think we'd handle not adding
the alias text to history the way we've been doing in other cases by
checking INP_* flags, which is much less hit and miss.  That ought not
to be too difficult, but I haven't really got my mind round the
consequences yet.

Everything else I can think of is a bit of a hack (and surely we'd never
etc. etc.)

Looks fine.  I'll try to expand it when it appears.
