In one sense neither is correct, since $\ldots$ in any version of TeX
I have ever used works only in math mode.<br>
I find that useful, since the $ of math mode protects the space on
either side of the macro. There are probably several views of how to
use the three-dot graphic but, in the U. S. it is is regularly given an
interword space to both left and right. The four-dot graphic for
sentence-end, on the other hand should not have a space to the left.
If you want a really acceptable $\fourdots$ macro you need to build on
Knuth's macro for three dots, using a math mode dot and regular math
mode spacing.<br>
<br>
If you are likely to need $\fourdots$ it is worth the effort.
\def\fourdots{\mathinner{\ldotp\ldotp\ldotp\ldotp}}<br>
<br>
Some European styles seem to prefer the three-dot graphic with no
space on either side, which is odd in a style wich often puts a space
on either side of a colon.<br>
