invarg(a,b) - "invalid argument", but how a and b enter the message? invarg_1_to_2(a,b) is somewhat easier to read: "invalid argument 'a' to 'b'" Audit of usage revealed a number of bad uses, with too long messages. text data bss dec hex filename 938848 932 17448 957228 e9b2c busybox_old 938788 932 17448 957168 e9af0 busybox_unstripped Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
