contrib: make editmerge look for merge markers at the beginning of the line This fix adds a caret to the start of the regex looking for merge markers. This avoids the issue arises when you've real merge conflicts in a file that tests for the existance of merge markers in test output. Editmerge will not open on the fake/tested merge markers because they'll be indented in.
