Adding -first-item and -last-item. [magnars/dash.el#17]
Release 1.8.0
Fix second example for -last/first-item
Fix incorrect alias checking in docs--signature

help-split-fundoc expects the function symbol to be the function
name used in the docstring. Since we only use help-split-fundoc for
subrs, this isn't an issue in practice, because subrs use
`(fn some-arg some-other-arg)` rather than an explicit name.

Still, the boolean ought to do what it says it's doing.
