Re: [RFD] Deepen the git directory structure a bit.

[Linus Torvalds <torvalds@linux-foundation.org>]

Btw, here's a new version of this without the 'builtin.h' rename. This was 
basically created with:

	for i in builtin-*; do git mv $i $(echo $i | sed 's:builtin-:builtin/:'); done
	sed 's:builtin-:builtin/:' Makefile > Makefile.new
	mv Makefile.new Makefile
	 ... add '-I.' to BASIC_FLAGS in 'Makefile' ...
	git commit -a

and it leaves the issue of what to do with the header files for later.

For example, maybe somebody would want to split up the makefile so that 
the 'builtin' subdirectory gets built all on its own. In which case you'd 
do a "-I.." there instead. Or maybe somebody wants to move the header 
files to a directory of their own, separate from either the regular C 
files _and_ the builtin commands.

So to not even weigh in on that whole discussion, this _just_ moves the 
builtin-* files, and adds the currently minimal "-I." to the makefile.

Subject: [PATCH] Move 'builtin-*' into a 'builtin/' subdirectory

This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of

	[torvalds@nehalem git]$ em buil<tab>
	Display all 180 possibilities? (y or n)
	[torvalds@nehalem git]$ em builtin-sh
	builtin-shortlog.c     builtin-show-branch.c  builtin-show-ref.c
	builtin-shortlog.o     builtin-show-branch.o  builtin-show-ref.o
	[torvalds@nehalem git]$ em builtin-shor<tab>
	builtin-shortlog.c  builtin-shortlog.o
	[torvalds@nehalem git]$ em builtin-shortlog.c

you get

	[torvalds@nehalem git]$ em buil<tab>		[type]
	builtin/   builtin.h
	[torvalds@nehalem git]$ em builtin		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/sh<tab>	[type]
	shortlog.c     shortlog.o     show-branch.c  show-branch.o  show-ref.c     show-ref.o
	[torvalds@nehalem git]$ em builtin/sho		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/shor<tab>	[type]
	shortlog.c  shortlog.o
	[torvalds@nehalem git]$ em builtin/shortlog.c

which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.

NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead.  I think bash has some cut-off
around 100 choices or something.

So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion.  But you can
simulate that by using 'ls' instead, or something similar.
