problem repeat entry for a number

[source liu]

hi list,

i know one should repeat a command by C-u + <num> + command,  for
'aaaaaaa' just type C-u 8 a.

but i've come across to a problem such as '99999999',  that doesn't
work properly i'm afraid. C-u 9 9 would treat the 9 9 as '99' which
means 99 times and expecting next input.  Is there any suggestion to
input such a case.

Regards.
