bug#4039: C-x 8 RET with prefix arg doesn't repeat character

[Juri Linkov]

Typing

  C-u 5 C-x 8 ' a

is supposed to insert 5 characters of á in a row
(modulo the reported bug#4037).

However, typing

  C-u 5 C-x 8 RET E1 RET

inserts just 1 character (`E1' is the code point of á).

I propose to fix `ucs-insert' to accept the same arguments
as `insert-char', i.e. `character', `count' and `inherit':
