expand --pretty=format color options
Currently, the only colors available to --pretty=format
users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.
Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:
git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'
to emulate --pretty=oneline, or even
git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'
if you want to relive the awesomeness of 4-color CGA.

log: handle integer overflow in timestamps
If an ident line has a ridiculous date value like (2^64)+1,
we currently just pass ULONG_MAX along to the date code,
which can produce nonsensical dates.
On systems with a signed long time_t (e.g., 64-bit glibc
systems), this actually doesn't end up too bad. The
ULONG_MAX is converted to -1, we apply the timezone field to
that, and the result ends up somewhere between Dec 31, 1969
and Jan 1, 1970.
However, there is still a few good reasons to detect the
overflow explicitly:
1. On systems where "unsigned long" is smaller than
time_t, we get a nonsensical date in the future.
2. Even where it would produce "Dec 31, 1969", it's easier
to recognize "midnight Jan 1" as a consistent sentinel
value for "we could not parse this".
3. Values which do not overflow strtoul but do overflow a
signed time_t produce nonsensical values in the past.
For example, on a 64-bit system with a signed long
time_t, a timestamp of 18446744073000000000 produces a
date in 1947.
We also recognize overflow in the timezone field, which
could produce nonsensical results. In this case we show the
parsed date, but in UTC.

logmsg_reencode: lazily load missing commit buffers
Usually a commit that makes it to logmsg_reencode will have
been parsed, and the commit->buffer struct member will be
valid. However, some code paths will free commit buffers
after having used them (for example, the log traversal
machinery will do so to keep memory usage down).
Most of the time this is fine; log should only show a commit
once, and then exits. However, there are some code paths
where this does not work. At least two are known:
1. A commit may be shown as part of a regular ref, and
then it may be shown again as part of a submodule diff
(e.g., if a repo contains refs to both the superproject
and subproject).
2. A notes-cache commit may be shown during "log --all",
and then later used to access a textconv cache during a
diff.
Lazily loading in logmsg_reencode does not necessarily catch
all such cases, but it should catch most of them. Users of
the commit buffer tend to be either parsing for structure
(in which they will call parse_commit, and either we will
already have parsed, or we will load commit->buffer lazily
there), or outputting (either to the user, or fetching a
part of the commit message via format_commit_message). In
the latter case, we should always be using logmsg_reencode
anyway (and typically we do so via the pretty-print
machinery).
If there are any cases that this misses, we can fix them up
to use logmsg_reencode (or handle them on a case-by-case
basis if that is inappropriate).

expand --pretty=format color options
Currently, the only colors available to --pretty=format
users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.
Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:
git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'
to emulate --pretty=oneline, or even
git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'
if you want to relive the awesomeness of 4-color CGA.

users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.
Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:
git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'
to emulate --pretty=oneline, or even
git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'
if you want to relive the awesomeness of 4-color CGA.
