Actually, after reading the patch again, I think it is better to be less
intrusive and add the error message *just* for the gdb case, as it is
right now:
-- snipsnap --
export GIT_EXEC_PATH GITPERLLIB PATH GIT_TEXTDOMAINDIR
+if test -n "$TEST_GDB_GIT"
+then
+ exec gdb -args "${GIT_EXEC_PATH}/@@PROG@@" "$@"
+ echo "Could not run gdb -args ${GIT_EXEC_PATH}/@@PROG@@ $*" >&2
+ exit 1
+fi
+
exec "${GIT_EXEC_PATH}/@@PROG@@" "$@"
