Update the long comment explaining it.
m4_require no longer writes an ``is required by'' line to the
execution stack. It contains only one bit of non-redundant
information: that the macro was required, not called. And even
this bit is useless in most situations: have you ever met a macro
which both calls and requires the same macro?

Extracted from AS_SHELL_SANITIZE.

macros.
