Weird size of tabs

[Br31zh]

When using tabs for indentation, the first one seems to start behind the line numbers, and then look a lot shorter than the other ones.

Expected:

# For all dirs and subdirs
for dir in **/ ./
do
	# Ignore symlinks
	if [[ -h "${rootdir}/${dir::-1}" ]]
	then
		continue
	fi
done

Result (simulated with space):

# For all dirs and subdirs
for dir in **/ ./
do
  # Ignore symlinks
  if [[ -h "${rootdir}/${dir::-1}" ]]
  then
          continue
  fi
done
