There is no setenv() in Solaris 5.8.  The trivial calls to
setenv() were replaced by putenv() in a much earlier patch,
but setenv() was used again in git.c.  This patch just adds
a compat/setenv.c.

The rule for building git$(X) also needs to include compat.
objects and compiler flags.  Those are now in makefile vars
COMPAT_OBJS and COMPAT_CFLAGS.

This hopefully concludes the latest updates that changes the
behaviour of the merge on an unsuccessful automerge.  Instead of
collapsing the conflicted path in the index to show HEAD, we
leave it unmerged, now that diff-files can compare working tree
files with higher stages.

The "update-index followed by checkout-index" chain served two
purposes -- to collapse the index to "our" version, and make
sure that file exists in the working tree.  In the recent update
to leave the index unmerged on conflicting path, we wanted to
stop doing the former, but we still need to do the latter (we
allow merging to work in an un-checked-out working tree).

Fingers of some "git diff" users are trained to do --name-only
which git-ls-tree unfortunately does not take.  With this,

	cd sub/directory && git-ls-tree -r --name-only ..

would show only the names not object names nor modes.  I threw
in another synonym --name-status only for usability, but
obviously ls-tree does not do any comparison so what it does is
the same as --name-only.

drivers/net.

	git-ls-tree -d -r HEAD -- drivers/net/

The old (new) behaviour was that it only shows trees if the object is
specified exactly, and recursive is not set. That makes sense, because
there is obviously nothing else it can show for that case.

However, with the new "-t" option, it will show the tree even with "-r",
as it traverses down into it.

NOTE! This also means that it will show all trees leading up to that tree.

For example, if you do a

	git-ls-tree -t HEAD -- drivers/char/this/file/does/not/exist

it will show the trees that lead up to the files that do not exist:

	[torvalds@g5 linux]$ git-ls-tree -t HEAD -- drivers/char/this/file/does/not/exist
	040000 tree 9cb687b77dcd64bf82e9a73214db467c964c1266    drivers
	040000 tree 298e2fadf0ff3867d1ef49936fd2c7bf6ce1eb66    drivers/char
	[torvalds@g5 linux]$

and note how this is true even though I didn't specify "-r": the fact that
I supplied a pathspec automatically implies "enough recursion" for that
particular pathspec.

I think the code is cleaner and easier to understand too: the patch looks
bigger, but it's really just splitting up the "should we recurse into this
tree" into a function of its own.

After thinking about it more, I realized that much of the change
I did on top of Linus' version does not make much sense.  This
commit reverts it so that it by default shows diffs with stage0
paths or stage2 paths with working tree; the unmerged stage to
use can be overridden with -1/-2/-3 option (-2 is the default so
essentially is a no-op).

When the index file is unmerged, we are by definition in the
middle of a conflicting merge, and we should show the diff with
stage 2 by default.  More importantly, paths without conflicts
are updated in the working tree and collapsed to stage0 in the
index, so showing diff with stage0 at the same time does not
hurt.  In normal cases, stage0 entries should be in sync with
the working tree files and does not clutter the output.  It even
helps the user to realize that the working tree has local
changes unrelated to the merge and remember to be careful not to
do a "git-commit -a" after resolving the conflicts.

When there is no unmerged entries, giving diff_unmerged_stage a
default value of 2 does not cause any harm, because it would not
be used anyway.  So in all, always showing diff between stage0
paths and unmerged entries from a stage (defaulting to 2) is the
right thing to do, as Linus originally did.
Signed-off-by: NJunio C Hamano <junkio@cox.net>

When automerge fails, we used to collapse the path to stage0
from "our" branch, to help "diff-files" users to view the
half-merged state against the current HEAD.  Now diff-files has
been taught how to compare with unmerged stage2,leaving them
unmerged is a better thing to do, especially this prevents the
unresolved conflicts to be committed by mistake.

While resolving conflicted merge, it was not easy to compare the
working tree file with unmerged index entries.  This commit
introduces new options -1/-2/-3 (with synonyms --base, --ours,
and --theirs) to compare working tree files with specified
stages.

When none of these options are given, the command defaults to -2
if the index file is unmerged, otherwise it acts as before.

add -p, and lack of -B*, -C* nor -M* to add -M to the flags
