If we were to add /usr/bin to beginning of PATH when the user runs 
/usr/bin/git I think that would be more surprising than adding 
GIT_EXEC_PATH which is what we do now. When we add GIT_EXEC_PATH to the 
beginning of PATH we only affect the lookup of git's programs. If 
instead we added /usr/bin to the beginning that would affect the lookup 
of many unrelated programs.
