You can ask to print out "raw" format (full headers, full body),
"medium" format (author and date, full body) or "short" format
(author only, condensed body).
Use "git-rev-list --pretty=short HEAD | less -S" for an example.

It's really just the header printign function from diff-tree.c,
and it's usable for other things too.

This is useful for when we want to insert the next one after
this new one, for example.

object.
A fair number of the users potentially want to look at the
commit objects more closely, and if you worry about memory
leaking in certain applications, you can always do a
free(commit->buffer);
commit->buffer = NULL;
by hand after parsing them.

Add <limits.h> to the include files handled by "cache.h", and remove
extraneous #include directives from various .c files. The rule is that
"cache.h" gets all the basic stuff, so that we'll have as few system
dependencies as possible.

This adds knowledge of delta objects to fsck-cache and various object
parsing code. A new switch to git-fsck-cache is provided to display the
maximum delta depth found in a repository.

It's pretty much the same as "lookup_commit()", but it will take
tags too, and look up the commit (if any) associated with them.

It turns out that parse_object() is loading and decompressing given
object to free it just before calling the specific object parsing
function which does mmap and decompress the same object again. This
patch introduces the ability to parse specific objects directly from a
memory buffer.
Without this patch, running git-fsck-cache on the kernel repositorytake:
real 0m13.006s
user 0m11.421s
sys 0m1.218s
With this patch applied:
real 0m8.060s
user 0m7.071s
sys 0m0.710s
The performance increase is significant, and this is kind of a
prerequisite for sane delta object support with fsck.

This patch fixes memory leaks in parse_object() and related functions;
these leaks were very noticeable when running git-fsck-cache.

Introduce xmalloc and xrealloc to die gracefully with a descriptive
message when out of memory, rather than taking a SIGSEGV.

That would SIGSEGV.

The type doesn't come from the parsing, the type also has to match the usage.

Otherwise we can have objects without a type, which is not good.

Make pop_most_recent_commit() return the same objects multiple times, but only
if called with different bits to mark.
This is necessary to make merge-base work again.

Otherwise any merges will make the parent list explode.

This adds a function for inserting an item in a commit list, a function
for sorting a commit list by date, and a function for progressively
scanning a commit history from most recent to least recent.

The old revision.h helper header isn't used any more, but I never noticed
it until I started grepping for ULONG_MAX users.
