Stitch together multiple matches from single line

[Ingramz]

Description of the Change

This pull request intends to fix the representation of multiple matches found on a single line.

To render a line of find results, multiple entries of ~100 characters of context and positional information about the context must be combined into single line, however the current implementation does not do this very well and pieces of text get cut off mid-line. Sometimes these 100 character segments may overlap in various ways, other times they are apart.

Example 1 - search matches are separated by long pieces of text

1000 words of padding with unique number appended to each of them
Before:

After:

Example 2 - previous match context contains the next match.

This was handled well enough by the previous algorithm

Example 3 - search matches between two segments are not contained in eachother, but their surrounding contexts overlap.

Before:

After:

Alternate Designs

The search library, scandal, could be made to return the entire line with ranges containing the matches, then stitching of multiple pieces of text would not be required.

Benefits

Always displays the full context of all matches where overlapping parts are combined.

Possible Drawbacks

None that I can see.

Applicable Issues

Haven't looked, but there could definitely be some.
