* In other programs I got rid of this complicated buffer switching,

* see the malloc() pool really getting fragmented. Maybe it

*

*
* nxtbuf is an array of pointers that contains malloc()'d buffers
* to hold our component text. used_buf is an array of struct comp
* pointers that holds pointers to component structures we found while
* processing a message.
*
* We read in the message with m_getfld(), using "tmpbuf" as our
* input buffer. tmpbuf is set at the start of message processing
* to the first buffer in our buffer pool (nxtbuf).
*
* Every time we find a component we care about, we set that component's
* text buffer to the current value of tmpbuf, and then switch tmpbuf
* to the next buffer in our pool. We also add that component to
* our used_buf pool.
*
* When we're done, we go back and zero out all of the component
* text buffer pointers that we saved in used_buf.
*
* Note that this means c_text memory is NOT owned by the fmt_module
* and it's our responsibility to free it.
