Problems in search & highlight

[jerch]

Entering this line with lots of spaces in the demo:

echo -e '                                          http://example.com      http://example.com'

pressing enter and searching for http shows two bugs:

1. the first result gets highlighted in the line above - imho related to some trimming of white spaces from right (maybe the empty vs. space cell problem? see Buffer performance improvements #791 (comment))
2. the second possible match in every line gets never highlighted

Problem one is new in master, problem two is also in 3.7. Have not tested older releases.

Problem 2 is captured in #1654
