Find content should not clear filtered rows

[stsymbaliuk]

Or in other words: Find content matching regex and highlight matches should work in filtered rows if filter applied with &<regex>.

Current behaviour:

• Open file cars_100.csv
• Filter rows with "Bronze": &Bronze;
• Search for "Subaru": /Subaru;
• Filter cleared, text on line 20 is found.
  

Expected behaviour:

• Open file cars_100.csv
• Filter rows with "Bronze": &Bronze;
• Search for "Subaru": /Subaru;
• Filter should not be cleared. Search should be performed only for filtered lines. Text on line 43 should be found.

In my opinion current behaviour should be changed. csvlens should work with filtered text in a similar way as less or bat.
