This allows us to run git, when using the script from bin-wrappers, under
other programs. A few examples for usage within testsuite scripts:
debug git checkout master
debug --debugger=nemiver git $ARGS
debug -d "valgrind --tool-memcheck --track-origins=yes" git $ARGS
Or, if someone has bin-wrappers/ in their $PATH and is executing git
outside the testsuite:
GIT_DEBUGGER="gdb --args" git $ARGS
GIT_DEBUGGER=nemiver git $ARGS
GIT_DEBUGGER="valgrind --tool=memcheck --track-origins=yes" git $ARGS
There is also a handy shortcut of GIT_DEBUGGER=1 meaning the same as
GIT_DEBUGGER="gdb --args"

Finally getting back to this now that I have tied up all loose ends
with the directory rename detection series (or at least I hope they
are all tied up).
There is only one change since v2:
s/DBG_FLAGS/GIT_DEBUGGER/, as suggested by Dscho
