By default, "make doc" generates the manpages and htmldocs in the
Documentation directory, but you may want to change this depending
on the target environment, e.g. to include 'pdf'.  Introduce a new
Makefile variable DEFAULT_DOC_TARGET to allow customizing this.

The primary motivation is to let us check documentation patches with

    $ DEFAULT_DOC_TARGET=git-push.1 make doc

but it is not so far-fetched to imagine that Windows users may want to
omit manpages with

    $ DEFAULT_DOC_TARGET=html make doc

or somesuch; this lets interested people to enhance the install-doc
target in a similar way.

Makes sense (we have DEFAULT_TEST_TARGET for similar reasons).

Wouldn't it be just as easy to say:

  $ make -C Documentation git-push.1

?

That use case makes a lot more sense to me (or more likely setting it in
config.mak).

No change to Documentation/Makefile? So this will work:

  $ echo DEFAULT_DOC_TARGET=html >config.mak
  $ make doc

but this will not:

  $ cd Documentation
  $ make

Why not do it like this:

diff --git a/Documentation/Makefile b/Documentation/Makefile
index 267dfe1..ca10313 100644

which covers both cases? That is also how we handle DEFAULT_TEST_TARGET.

I actually had "ifeq ($(uname_S),Windows)" at the top-level in mind,
not config.mak.  I think that is far more important use case than
going down to Documentation yourself and run make there (which is
not a workflow I deeply care about in the first place).

So here is a proposed update based on your idea, to be squashed on
top (i.e. the change to the top-level Makefile in the posted patch
is not reverted).

Does it make sense?

The change to Documentation/Makefile makes sense, but what then is the
point of the second half of this hunk from your original:

@@ -2468,10 +2476,10 @@ $(XDIFF_LIB): $(XDIFF_OBJS)
 $(VCSSVN_LIB): $(VCSSVN_OBJS)

 doc:

+	$(MAKE) -C Documentation $(DEFAULT_DOC_TARGET)
 
 man:
 	$(MAKE) -C Documentation man

We know that "all" is simply a redirect to DEFAULT_DOC_TARGET internally
within the documentation Makefile, and we know that it is propagated by
the export line above.  I do not think it creates the wrong behavior,
but it is unnecessary, and omitting a target at all demonstrates to a
reader how they can get the same behavior from within Documentation
(namely by running just "make").

Hmm. Unfortunately that does not work from within Documentation, because
Documentation/Makefile never gets to see our default-system tweaks (it
sees only config.mak).

I know it is a case you do not care about (and nor do I; if I use this
at all, it would be to limit my build by setting the variable in my
config.mak), but it highlights a subtle issue. The subdir Makefiles
receive their config from config.mak.autogen and config.mak, but never
get to see any of the default tweaks we do based on $(uname). Which the
contents of config.mak could very well depend on, if somebody were
trying to be very clever.

Would it make sense to pull all of our platform-specific tweaks out into
a config.mak.platform (right before config.mak.autogen)? That would be
less surprising for cases like this, and I think it would make the
Makefile a lot more readable.

Something like the patch below. Note that you could then base even more
decisions on the existing DEFAULT_HELP_FORMAT that is already in the
Makefile (and after my patch, in config.mak.defaults). For example, when
it is set to html, make both the default build and install targets in
Documentation/Makefile do html instead of man.

Yeah, modulo that the "defaults" is tracked and does not have to
have the dash before "include" (it is an error if it is missing,
no?).  It may want to be named with s/defaults/autodetect/, though.

Yeah, sorry, mindless copying on my part from the lines below. It
clearly should not have the "-".

I'm fine with something besides "defaults". I meant it to be "these are
the config defaults before you tweak them", but yeah, it is more like
"these are the config options we picked up from uname".

Let's put this on hold in the "possibly a good direction to go in"
pile, and defer it to post 1.8.0; I haven't even looked at (and do
not plan to before the release) these "auto-detect" bits are all
safe to be included in Makefiles in subdirectories.

Oh by the way, by "this (on hold)" I meant not just your "move the
default-by-platform to a separate include", but the whole "a
platform may not want manpages" topic.  The patch posted was merely
me wanting to format git-push.txt and nothing else when sanity
checking a patch to that file, and it is insufficient for the
purpose of "a platform may not want manpages" without a matching
change to the install target.

Even though your "include" thing was primarily done to make it
easier to include it from Makefiles in subdirectories, I very much
like it even without that benefit.  The change makes it clear that
there is another platform specific bit after '-include config.mak'
(yes, I am looking at you, Darwin), which is a huge eyesore we would
want to do something about.
