I work with wordpress a lot, and sometimes I changed wordpress core files temporarily in order to understand what is going on, especially when debugging. Today I got a little surprise. When I was ready to commit my changes to my git repository, I noticed that git status was marking one of wordpress' files as not staged for commit. I remember I had reverted all the changes I did to that file before closing it, so I decided to use diff to see what had changed. I compared the file on my project with the file on the wordpress copy that I keep in my downloads directory. It turns out the files differ at the very end. diff indicates that the there is a newline missing at the end of the original file:
1724c1724 < } \ No newline at end of file --- > }
I never even touched that line. The changes I made where somewhere in the middle of a large file. This leads me to think that vim added a newline character at the end of the file. Why would that happen?
