Ignoring super long lines

[andrewthad]

One thing that often gets in my way when I'm searching for things is that I'll get matches for random json and xml files that are rendered as one line. I never want to see these, so I looked through the man page and found an interesting flag:

--print-long-lines:
     Print matches on very long lines (> 2k characters by default)

Cool. But there are two problems. The first one is a functional issue (or maybe just my ignorance) and the second is a feature request.

1. The man page entry seems to indicates that by default this flag is off by default. But it isn't. When I run ag on my computer, it prints a match on a line with 1368810 characters. And I don't see a way to turn this flag off either. There isn't a --noprint-long-lines flag mentioned in the man page. So basically, I don't see how to actually get the actually get the line-filtering behavior that the man page indicates is possible.
2. Can we configure what is considered a "very long line"? In my case, it's really the lines with more than 100 characters that I would like to filter out. I would like to see a flag `--long-line-length=2000' so that I could have more control over this.

Regardless, thanks for all the hard work on this awesome tool. It is enormously helpful in my workflow, and I hope that it can become even more so.

Duplicate of #189, I think.

It appears so. I guess since that issue has been open two years and seems unlikely to get fixed, maybe my request could instead be to remove --print-long-lines from the documentation, since it only confuses people who expect it to work.

@andrewthad I agree. I've submitted https://github.com/ggreer/the_silver_searcher/pull/706 to do that. I've also submitted https://github.com/ggreer/the_silver_searcher/pull/707 to fix the underlying issue.
