log: respect graphshorten on terminal nodes (collapsing o-~ to just o~)

Internally we have a custom template that's inspired by ones that we have seen
in the community. Normally, this looks something like:

    o  0834ec17 spectral tip
    |  crecord: support x to toggle single, X to toggle a range
    o  ee932990 spectral @
    |  filemerge: allow specifying $hgeditor as merge-tools.X.executable
    @  66f04611 matt_harbison
    |  cext: fix truncation warnings in revlog on Windows
    o  42cc76d0 matt_harbison
    |  cext: fix revlog compiler error on Windows
    ~
    o  bd63ada7 stable boris
    |  phases: drop dead code in `newheads`
    ~

With graphshorten on, and the descriptions of the public nodes hidden, it looks
like this, note that the commits right before the ~ are still "full height":

    o  0834ec17 spectral tip
    |  crecord: support x to toggle single, X to toggle a range
    o  ee932990 spectral @
    |  filemerge: allow specifying $hgeditor as merge-tools.X.executable
    @  66f04611 matt_harbison
    o  42cc76d0 matt_harbison
    |
    ~
    o  bd63ada7 stable boris
    |
    ~

This patch makes them look like this, removing the | but keeping the ~:

    o  0834ec17 spectral tip
    |  crecord: support x to toggle single, X to toggle a range
    o  ee932990 spectral @
    |  filemerge: allow specifying $hgeditor as merge-tools.X.executable
    @  66f04611 matt_harbison
    o  42cc76d0 matt_harbison
    ~
    o  bd63ada7 stable boris
    ~

This originally removed the ~s entirely, but this was determined to be too much
information loss and potentially confusing. This would have looked like the
following (note that the last commit is on a different branch than all of the
ones above it, and they are *not* linearly related):

    o  0834ec17 spectral tip
    |  crecord: support x to toggle single, X to toggle a range
    o  ee932990 spectral @
    |  filemerge: allow specifying $hgeditor as merge-tools.X.executable
    @  66f04611 matt_harbison
    o  42cc76d0 matt_harbison
    o  bd63ada7 stable boris

All of these should be present:

All of these except 'a' should be present:

'd' in dc: True

These should be in reverse alphabetical order and read 'v?3':
d['d']: vd3
