config: do not reset pos when braces found

[RedSoxFan]

Fixes #3410

When a brace is found, the config file should not seek back to before
the brace, otherwise the brace will be read multiple times.

I think this would be better placed in the else block of the if (strcmp(line, "{") == 0), so that it skips empty lines.

[RedSoxFan]

The issue with that is the lines numbers for errors won't match the real file line number (note that this is already the case if the config file contains any continued lines since get_line_with_cont is assumed to be a single line.) Ideally, the numbers should be accurate to make finding and fixing the lines easier

I think your PR actually fixed EOF not empty lines

A fix for the continuation line problem would be good, too.

Thanks!

And an apology for completely forgetting how the code I wrote worked.

Was going to include it in this one, but decided it would be better as a separate PR. Going to work on it now.

I mean it still looks a lot nicer than the code I wrote months ago that you replaced haha
