"<i{" - when issued from a function - is not repeatable via "."

#include <stdio.h>

int main(int argc, char **argv)
{
xxx

return 0;
}
Contrary to e.g. ":normal! <i{" (or "<i{" for that matter)".", repetition doesn't work when issued from a function (in which case the last input command is repeated):

> gvim in.c
:so in.vim
/xxx
iyy<Esc>
:normal! <i{
.
.
=== OK ===
u
u
u
/xxx
<<
.
.
=== DIFFERENT ===
