ex/ex_txt.c: txt_dent: introduce sequence point between decrement and access
In particular, ensure the decrement is performed
before the modulo is subtracted from "scno".
Although most, if not all, compilers will perform
the decrement first even in the original code,
this is not guaranteed by the C language.
