Use horizontal lines instead of long diagonal lines during the
collapsing state of graph rendering.  For example what used to be:

    | | | | |
    | | | |/
    | | |/|
    | |/| |
    |/| | |
    | | | |

is now

    | | | | |
    | |_|_|/
    |/| | |
    | | | |

This results in more compact and legible graphs.

The original implementation considered the mode separately
from the rest of the hunks, asking about it outside the main
hunk-selection loop. This patch instead places a mode change
as the first hunk in the loop. This has two advantages:

  1. less duplicated code (since we use the main selection
     loop). This also cleans up an inconsistency, which is
     that the main selection loop separates options with a
     comma, whereas the mode prompt used slashes.

  2. users can now skip the mode change and come back to it,
     search for it (via "/mode"), etc, as they can with other
     hunks.

To facilitate this, each hunk is now marked with a "type".
Mode hunks are not considered for splitting (which would
make no sense, and also confuses the split_hunk function),
nor are they editable. In theory, one could edit the mode
lines and change to a new mode. In practice, there are only
two modes that git cares about (0644 and 0755), so either
you want to move from one to the other or not (and you can
do that by staging or not staging).

There's already 'd' to stop staging hunks in a file, but no explicit
command to stop the interactive staging (for the current files and the
remaining ones).  Of course you can do 'd' and then ^C, but it would be
more intuitive to allow 'quit' action.

Instead of doing the (potentially very expensive) "in_merge_base()"
check for each commit that might be pruned if it is unreachable, do a
preparatory reachability graph of the commit space, so that the common
case of being reachable can be tested directly.

This clarifies the pruning rules for unreachable commits by having a
separate helpder function for the unreachability decision.

It's preparation for actual bigger changes to come to speed up the
decision when the reachability calculations become a bottleneck.

When tags that points to tags are passed to fast-export, an error is given,
saying "Tag [TAGNAME] points nowhere?". This fix calls parse_object() on the
object before referencing it's tag, to ensure the tag-info is fully initialized.
In addition, it inserts a comment to point out where nested tags are handled.
This is consistent with the comment for signed tags.

If a tag object points to a tree (or another unhandled type), the commit-
pointer is left uninitialized and later dereferenced. This patch adds a
default case to the switch that issues a warning and skips the object.

fast-import doesn't have a syntax to support tree-objects (and some other
object-types), so fast-export shouldn't handle them. However, aborting the
operation is a bit drastic. This patch turns the error into a warning instead.
