Looking at a changed file from my git repo in Sourcetree, it has some legitimate changes in it. But when I compare versions of the file and look in the Sourcetree 'differences' pane, it is showing a line that (I believe) was unchanged. It show a red -, and green + for the same line #23, with the same text, same number of spaces, etc:
I guess my question is: why is this marked as a "difference"? Thanks for the help!
