Somewhere in the alias handling git turned hostile on fat fingers:

$ git showbranch
Failed to run command '': Is a directory

Does not happen here (nor on Cygwin 1.4.1.rc1).  Care to help
reproducing it?

Here's the complete procedure I used:

	$ git pull && make; # works ok
	$ make strip install; # works ok
	$ git showbranch
	Failed to run command '': Is a directory
	(confusion and puzzlement...)
	$ git checkout master; git reset --hard master; # works ok
	$ git pull; # gets nothing (I try stupid things first ;p)
	$ make clean install; # works ok
	$ git showbranch
	Failed to run command '': Is a directory
	$ git --version
	git version 1.4.1.rc1.g1ef9


It's reliably reproducible here. Notable though is that I have no 
.git/config in my git.git clone and no ~/.gitconfig (or ~/.gitrc or 
whatever), so the handle_alias() function never finds a config file to 
look for aliases in.

Either way, removing the variable "char git_command[MAX_PATH + 1];" from 
git.c:main() is correct since it's never used for anything but printing 
the (erroneous) error message above.
