pub static commandbn: LazyLock<builtin>Expand description
Port of static struct builtin commandbn from Src/exec.c:276.
c:275 — /* structure for command builtin for when it is used with -v or -V */
BUILTIN("command", 0, bin_whence, 0, -1, BIN_COMMAND, "pvV", NULL).
This is a SEPARATE descriptor from the BIN_PREFIX("command", …) row in
builtintab (which carries no handler at all): c:3209 swaps hn to this
one when command -v / command -V is seen, so the dispatch lands in
bin_whence with funcid BIN_COMMAND.
