Why does git occasionally write markup to my source code such as the following?
<<<<<<< HEAD
<component name="JavaScriptSettings">
<option name="languageLevel" value="ES6" />
</component>
=======
>>>>>>> 02d2be40f4d48e8bcddbd819c19e3c01c4e690c4
where everything between HEAD
and =======
is source code and the rest is markup git seems to have been using for tracking and merging changes. In my case, these appeared after attempting to remove a folder from the history using filter-branch:
Remove folder and its contents from git/GitHub's history
Is this possibly something IntelliJ is injecting?
