After ‘C-x v g’ (vc-annotate) typing ‘a’ (vc-annotate-revision-previous-to-line)
in the *Annotate* buffer on the earliest (initial) revision fails with:
Debugger entered--Lisp error: (error "Invalid argument to vc-annotate-warp-revision")
signal(error ("Invalid argument to vc-annotate-warp-revision"))
error("Invalid argument to vc-annotate-warp-revision")
vc-annotate-warp-revision(nil "...")
This patch provides a nicer message:

This is now fixed.
Another problem is that ‘vc-root-version-diff’ can't be used when
fileset is not available. But this command doesn't use fileset,
it uses the root directory, so this patch adds an optional
arg ‘fileset’ to ‘vc-diff-build-argument-list-internal’,
so ‘vc-root-version-diff’ can provide its own fake fileset
with the root directory:
