Issue

Wrapped lines are not being considered correctly in search. Because of that, findPrevious and findNext are skipping entries that match the searched pattern.

Proposed solution

I changed a bit how the findInLine works to use a SearchPosition object instead of param values.
That way we can update the startRow/startCol in the function and make sure the caller function will also consider them.

For reverse search:
The searchStart was being calculated incorrectly. Instead of using terminal.cols as the max value, we should consider that wrapped lines can have a startCol higher than this. (Ln. 163)

For regular search:
In case we have multiple entries of the search term in a single wrapped line, findNext was finding only the first entry. In case we find a wrapped line, we need to iterate back until we find the line start, while increasing the startCol. This will make us start the search in the correct line/col, and make sure we go through the whole wrapped line before going back to the start.
