git-merge-tree causes a null pointer dereference when a directory
entry exists in only one or two of the three trees being compared with
no corresponding entry in the other tree(s).
When this happens, we want to handle the entry as a directory and not
attempt to mark it as a file merge. Do this by setting the entries bit
in the directory mask when the entry is missing or when it is a
directory, only performing the file comparison when we know that a file
entry exists.

Versions of fast-export before v1.8.2 throws a bad 'reset' commands
because of a behavior in transport-helper that is not even needed.
We should ignore them, otherwise we will treat them as branches and
fail.
This was fixed in v1.8.2, but some people use this script in older
versions of git.
Also, check if the ref was a tag, and skip it for now.

If there's already a remote-helper tracking ref, we can fetch the
SHA-1 to report proper push messages (as opposed to always reporting
[new branch]).
The remote-helper currently can specify the old SHA-1 to avoid this
problem, but there's no point in forcing all remote-helpers to be aware
of git commit ids; they should be able to be agnostic of them.

Bazaar doesn't seem to be tested for multiple usage of branches, so

accessing the Branch objects only when needed.

If part of the merge was already pushed, we don't have the blob_marks

In order to do that, we need to store the marks of every file, so that
they can be fetched when needed. Unfortunately we can't tell bazaar that
nothing changed, we need to send the data so that it can figure it out
by itself.
And since it will be requesting a bunch of information by the file_id,
it's better to have a helper dict (rev_files), so that we can fetch it
quickly.

In the !delta_data error path of unpack_entry(), we run free(base).
This became a window for use-after-free() in abe601b (sha1_file:
remove recursion in unpack_entry, 2013-03-27), as follows:
Before abe601b, we got the 'base' from cache_or_unpack_entry(..., 0);
keep_cache=0 tells it to also remove that entry. So the 'base' is at
this point not cached, and freeing it in the error path is the right
thing.
After abe601b, the structure changed: we use a three-phase approach
where phase 1 finds the innermost base or a base that is already in
the cache. In phase 3 we therefore know that all bases we unpack are
not part of the delta cache yet. (Observe that we pop from the cache
in phase 1, so this is also true for the very first base.) So we make
no further attempts to look up the bases in the cache, and just call
add_delta_base_cache() on every base object we have assembled.
But the !delta_data error path remained unchanged, and now calls
free() on a base that has already been entered in the cache. This
means that there is a use-after-free if we later use the same base
again.
So remove that free(); we are still going to use that data.

So that we can have a nice zsh completion output:
% git <tab>
add -- add file contents to the index
bisect -- find by binary search the change that introduced a bug
branch -- list, create, or delete branches
checkout -- checkout a branch or paths to the working tree
clone -- clone a repository into a new directory
commit -- record changes to the repository
diff -- show changes between commits, commit and working tree, etc
fetch -- download objects and refs from another repository
grep -- print lines matching a pattern
init -- create an empty Git repository or reinitialize an existing one
log -- show commit logs
merge -- join two or more development histories together
mv -- move or rename a file, a directory, or a symlink
pull -- fetch from and merge with another repository or a local branch
push -- update remote refs along with associated objects
rebase -- forward-port local commits to the updated upstream head
reset -- reset current HEAD to the specified state
rm -- remove files from the working tree and from the index
show -- show various types of objects
status -- show the working tree status
tag -- create, list, delete or verify a tag object signed with GPG
And other niceties, like 'git --git-dir=<tab>' showing only directories.
For the rest, the bash completion stuff is still used.

There should be no functional changes.
The only reason I wrapped this code around a sub-function is because zsh
did the same in it's bashcompinit script in order to declare the special
variable 'words' as hidden, but only in this context.
There's no need for that any more since we access __git_main directly,
so 'words' is not modified, so there's no need for the sub-function.
In zsh mode the array indexes are different though.
