- fixed typo: had skipped '-Make' instead of 'Make' directory
- remove broken links first
* helps when file locations have changed
- filter out trailing 'lnInclude' from the <dir> spec
* this makes it easier to update existing lnInclude dirs:
find -name lnInclude -exec wmakeLnInclude -f {} \;
- reduced output noise when re-creating an identical link
