Files with .e suffix do not display properly in OpenGrok UI #2577
Description
Another team at my company has been using OpenGrok with our software for almost 2 years. They are using release 0.13 and are not having issues with the display of .e files. But their server is not reliable and is down frequently, so I installed the latest version (1.1-rc70 and then 1.1-rc76) on a different machine. It parses the .e files properly and gives the same search result line numbers as the older version. However, when the .e file is displayed on the screen, it sometimes doesn't detect end of line, and sometimes it skips part of the file, so the line numbers it gave don't resolve properly.
I will attach photos of the same code being shown in both versions of OpenGrok.
Here is the file incorrectly rendered on a server running 1.1-rc76
Here is the file correctly rendered on a server running 0.13.
I used a Hex editor to look at the files in question. I don't think the file type has anything to do with it. The places in the file where the UI gets messed up have double line feeds (0A 0A).
Here is a section of the code from what is displayed in the images. Line 00004B8C shows the first double line feed where the display starts to get messed up.
