------------------------------
Description:
aAtable with header. skip.header.line.count=1 does not skip the first line if it is blank, except in a fetch task.
To reproduce, create a csv table, ans set header. skip.header.line.count=1 in table properties.
In the table location, create a single file, with a blank (empty) first line, and say 2 further lines.
If you do a select * on it, you see 2 rows (correct)
If you do select count(\*) on it, you get 3 (incorrect)
