Hi,
I'm quite confused with a pattern to replace, I can't target 3 suspension points following a new line and followed by another character.
I want to add a space after these 3 points, thus only when they begin the line (I have another reg ex when they are preceeded by a space).

For instance, I'd like this ;

1
00:02:37,309 --> 00:02:39,516
Hello...

2
00:02:39,687 --> 00:02:42,641
...hi ...you.

to become ;

1
00:02:37,309 --> 00:02:39,516
Hello...

2
00:02:39,687 --> 00:02:42,641
... hi ...you.

I believed this could work but no ;

(\n)(\.{3})(\w)

replace by ;

$1$2 $3
