Import: Join lines of hard wrapped paragraph

[raineorshine]

Is accurate detection possible? Should we instead leave this to the user to fix with join + split?

The condition must be carefully constructed to avoid false positives (i.e. accidentally joining imported text that should be imported as separate lines).

✗ Text may not begin with a capital letter.
✗ Text may not contain any periods.

False positives:

Mr. Smith
Mrs. Smith

Steps to Reproduce

They assumed that the
census reflected the basic sociological facts. This it did, but
through the enumerative modality, the project also objectified social,
cultural, and linguistic differences among the people. The pan-
optical view that they were constructing led to the reification of
the territory as polity in which conflict, from the point of view of the rulers,
could only be controlled by their strong hand.

Current Behavior

Imported as separate lines.
