Wire up TO FILE for both LIST and DISPLAY: __dbList grows a 9th
parameter cFile, opens it (truncating any prior content) when non-
empty, and writes the formatted rows there via fmt.Fprintln. Default
behavior (no TO FILE) still goes to stdout.
std.ch gets two new rules placed *before* the regular LIST/DISPLAY
patterns so they win when TO FILE is present:
LIST [<v,...>] TO FILE <(f)> [OFF] [FOR] [WHILE] [NEXT] ...
DISPLAY [<v,...>] TO FILE <(f)> [OFF] [FOR] [WHILE] [NEXT] ...
Open failure raises a clear *HbError ("LIST/DISPLAY TO FILE: cannot
create <path> — <syscall reason>") so callers know exactly what went
wrong instead of getting partial-or-empty output.
TO PRINTER stays rejected via __dbNotImpl — Five doesn't drive a
printer port. Test coverage: tests/std_ch/test_list_to_file.prg
exercises four shapes (full LIST, single-row DISPLAY, OFF + FOR with
explicit fields, and confirms TO PRINTER still raises). Wired into
the std.ch runner so the regression suite now stands at 14/14.
Gates green:
go test ./... : PASS
FiveSql2 SQL:1999 : 43/43
Harbour compat : 56/56
std.ch suite : 14/14
