named branches are really confusing

[Neal Becker]

In my repo I have:
hg branches
pi4                            333:8b803d69d900
default                        324:7ad94909abfe (inactive)
nosplit                        179:1fb87f703baf (inactive)

hg id
8b803d69d900+ (pi4) tip

Now I clone it, using hg clone with no options.

The new clone:
hg branches
pi4                            333:8b803d69d900
default                        324:7ad94909abfe (inactive)
nosplit                        179:1fb87f703baf (inactive)

hg id
7ad94909abfe

I find this really confusing, and a real invitation to error.  I had
forgotten about the branches, and I expected the clone to be, well, a
clone.  Surprise, surpise!

Might I suggest that either:
1) A clone will by default be on the same branch as the repo it was cloned
form, or
2) Some kind of warning about this?
