Issue Unit fixer , \n are removed

[n-richaud]

I have an issue with some fixers , \n are removed . Example with this text :

## Verrückt und Harakiri 2
Am Tag nach dem

the fixer fiw the text like this

## Verrückt und Harakiri 2 Am Tag

Here the preg_match output of the regex of the fixer :

I found the problem is that \s match \n . So to fix this we should replace \s by his equivalent minus \n .

I foud this in the python doculentation of re lib :

When the UNICODE flag is not specified, it matches any whitespace character, this is equivalent to the set [ \t\n\r\f\v]. The LOCALE flag has no extra effect on matching of the space. If UNICODE is set, this will match the characters [ \t\n\r\f\v] plus whatever is classified as space in the Unicode character properties database.

So replace \s by \t\r\f\v can be a solution
