Sadly I found a bug with the current implementation for shell scripts:

ls -l /usr/sbin/update-fmtutil 
lrwxr-xr-x 1 root root 26 Aug 17 07:38 /usr/sbin/update-fmtutil -> update-tl-
stacked-conffile

cat /usr/sbin/update-fmtutil
#!/bin/bash -e
...
progname=$(basename "$0")
echo $progname
...
if [ "$progname" = "update-updmap" ] ; then
...
elif [ "$progname" = "update-fmtutil" ] ; then
...
else
  echo "Please call me either as update-updmap or update-fmtutil!"
  exit 1
fi

sh -c /usr/sbin/update-fmtutil
 update-tl-stacked-conffile
Please call me either as update-updmap or update-fmtutil!

./test_readlink /usr/sbin/update-fmtutil
bufsize = 27
'/usr/sbin/update-fmtutil' points to 'update-tl-stacked-conffile'

In this case the link name should not be resolved. Any ideas?
