Find multiple matches on the same line.

[mtimaN]

I modified find so that it can show multiple matches on the same line.

• Changed the last_match variable so that it holds both coordinates of the last match
• If a key has been found on the current row, the next search is performed in a slice starting after the key.

I fixed the linter error at the expense that parameter names are less suggestive. However I think the comments are insightful enough for the code to be readable.

I've realized that my code unfortunately doesn't work for searching backwards on the same line and I can't find a solution that wouldn't break the line count. :(
