Ok, there's something weird going on here.  On hera:

rmk@hera:/pub/scm/linux/kernel/git/torvalds/linux-2.6.git(0)$ SHA1_FILE_DIRECTORY=./objects fsck-cache
expect dangling commits - potential heads - due to lack of head information

In my repository:

$ fsck-cache

These two objects appear to be tags according to cat-file -t on hera,
so these probably aren't the cause - it's more likely that git-pasky-0.7
doesn't know how to handle these objects.

Ok.  So.

rmk@hera:/pub/scm/linux/kernel/git/torvalds/linux-2.6.git(0)$ SHA1_FILE_DIRECTORY=./objects merge-base c60c390620e0abb60d4ae8c43583714bda27763f bdceb6a0162274934386f19f3ea5a9d44feb0b20
bdceb6a0162274934386f19f3ea5a9d44feb0b20

$ merge-base c60c390620e0abb60d4ae8c43583714bda27763f bdceb6a0162274934386f19f3ea5a9d44feb0b20
e8108c98dd6d65613fa0ec9d2300f89c48d554bf

Hmm.  At this point, I think we need something which graphically
shows the layout of the commit tree to work out what's going on,
and why my merge-base picked that particular commit id.

However, at this point, I think I can say that git obviously isn't
working as designed for me.
