Follow-up to the previous commit on this branch, both wording fixes.
- The sentence this branch deleted was the page's only description of the row
count when no search is active - and that is the case where the count really
can exceed the rows displayed (viewdata reports count(*) for the filtered
view while the grid stops at DC_MAXOBS_WEBVIEW). State it, instead of leaving
the page silent on the path readers use most.
- "returns the first 500" claims an ordering the search does not apply: the
search is a WHERE clause with no ORDER BY, so which 500 come back is whatever
the engine hands over first. Say "returns 500 of them".
Checked against viewdata.sas and mp_searchdata.sas on main: the search path
passes outobs=DC_MAXOBS_WEBVIEW to mp_searchdata, which caps the result dataset
in the same data step that builds it, and viewdata takes its row count from that
dataset - so for a search the count and the rows are capped together.
The row count next to the table name is the capped count, not the total
number of matches. A search that matches more rows than DC_MAXOBS_WEBVIEW
returns the first 500 and reports 500, so the count does not rise above the
cap even when many more rows match.
