Back then I didn't know that the Emacs coding style prefers signed int.
Also, in the meantime I found a few more instances where arguments
were being counted with int, which may truncate counts on 64-bit
machines, or EMACS_INT, which may be unnecessarily wide.

to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
* callint.c (Fcall_interactively): Check arg count for overflow,

for 'varies' array, so that we needn't bother to check its size
calculation for overflow.
