A saner thing to do, instead of explaining away the lack of HEAD as
"the creator of the bundle did not bother to name it", might be to
automatically add an artificial HEAD to the resulting bundle when
the arguments given to specify the "range" do not have any negative
ones (because by definition such a bundle is unsuitable for use with
"git clone" [*1*]), and HEAD is not among the refs.

The heuristics to pick what to record as the artificial HEAD could
vary, though. Without thinking things through...

 * When only one positive ref is given, use it (sort of obvious);

 * When two or more positive refs are given, and the current branch
   is one of them, use that;

 * Otherwise, pick the "first" positive ref given from the command
   line.

perhaps?


[Footnote]

*1* Strictly speaking, this condition could be loosened, as long as
cloning side uses an appropriate --depth, but I do not know such an
"advanced use case" needs a hand-holding change to add a HEAD that
was not asked by the user.
