We tend to give --full-tree option to individual subcommands where it
makes sense to get the same effect.

One problem with a global "git --cdup" is to sensibly handle pathspecs
given from the command line.  You would likely want

	$ cd Documentation
        $ git --cdup grep -e info pu Makefile '*.txt'

to still refer to Makefile relative to Documentation/ directory (imagine
typing "Makef<TAB>" to complete while forming that command line) while
looking for '*.txt' files everywhere in the tree, but only individual
commands can tell which parameters are pathspec in argv[].  Hence the
subcommands have to be aware of the wish (--cdup or --full-tree) of the
user to affect the full tree, not limited to the current working
directory.
