From: sawaya To: bug-gnu-emacs@gnu.org Subject: 23.3; ediff can't ignore whitespace regarding tabs vs spaces Date: Tue, 17 Mar 2015 14:20:58 -0600 Message-ID: <874mpjided.fsf@fractus.cs.utah.edu> --text follows this line-- I was working on a major merge (of two versions of a file) using ediff (the file that was giving me trouble was about 10k lines long). I was getting HUGE diference regions and also it was strange that I had varying regions between the files where I didn't discern any difference in the text. This was after enabling (with ##) the option to ignore differences in whitespace. After I reset the tabs in both files (by reindenting the entire files with emacs), things went much better and I was able to get through the merge process. I can provide you with copies of the files -- they do happen to be open source.
