Shouldn't reflog of a symbolic ref contain (or also contain) the name of
pointee ref, instead of the resolved value? Than we could still get the exact
past revisions by looking at the pointee reflog by time, but could also get
the past branch names.

It would require an extension to the commitish syntax for specifying how to
resolve the pointee. Eg. HEAD^{1} would mean the previous sha1, HEAD^{1}{}
would mean the previous branch (but current value of it), and, by extension,
HEAD^{}{1} could mean previous value of currently selected branch.

Hm, the slight problem seems to be, that users would want previously checked
out branch even though commits were already done to the current one, so it is
not the previous reflog entry anymore...
