[R] Issue with 95% CI using MASS{confint}

[sami.toppinen at kolumbus.fi]

I encountered the same problem today. It seems to occur only when you 
use exactly 95 % as the confidence level. For example:

> confint(g1)
Waiting for profiling to be done...
        2.5%      97.5%
a0 1.257512   1.330881
KP       NA 163.862932
> confint(g1, level = 0.95)
Waiting for profiling to be done...
        2.5%      97.5%
a0 1.257512   1.330881
KP       NA 163.862932
> confint(g1, level = 0.950001)
Waiting for profiling to be done...
          2.5%      97.5%
a0   1.257512   1.330881
KP 125.814534 163.862996
> confint(g1, level = 0.949999)
Waiting for profiling to be done...
          2.5%      97.5%
a0   1.257512   1.330881
KP 125.814709 163.862802
