Multiple consecutive hyphens should be replaced by a proper Unicode dash or bar

[DavidHaslam]

In the concatenated USFM file there are 113 matches to the regexp pattern -{2,}

I think these should be replaced by a proper Unicode character
U+2013 – EN DASH
U+2014 — EM DASH
U+2015 ― HORIZONTAL BAR
as appropriate for each context.

Check the spacing before and after each instance too! And aim for consistency rather than the present variable number of consecutive hyphens keyed for convenience.

There are also 8 instances of code point U+005F _ LOW LINE, 6 of which are single occurrences.
I take the view that these 6 should also be replaced by a proper Unicode dash or bar as appropriate.

The other location has a double __ at the end of Acts 28:25

\v 25 ਜਾਂ ਉਹ ਆਪਸ ਵਿੱਚ ਇੱਕ ਜ਼ਬਾਨ ਨਾ ਹੋਏ ਤਾਂ ਪੌਲੁਸ ਦੇ ਇਹ ਇੱਕ ਗੱਲ ਕਹਿੰਦੇ ਹੀ ਓਹ ਚੱਲੇ ਗਏ ਕਿ ਪਵਿੱਤ੍ਰ ਆਤਮਾ ਨੇ ਤੁਹਾਡੇ ਵੱਡਿਆਂ ਨੂੰ ਯਸਾਯਾਹ ਨਬੀ ਦੀ ਜ਼ਬਾਨੀ ਠੀਕ ਆਖਿਆ ਸੀ, *__

The asterisk just before the __ might be the residue of a note marker?
This instance needs to be more carefully reviewed.

There are in fact 76 asterisks in the complete text! See also issue #94
