Details:

Below are two 'grep -F' executions, one with -w, one without it.

The occurrences of XGET in recs.c do NOT appear at all in the -w execution.
And there are five instances of the word XGET in xcall.c, but the -w
execution
only reported four of them.  The failure to pick up recs.c is my main
concern
since I was looking for all modules that used the XGET function, and didn't
get
recs.c using -w.
