Subject: [PATCH] Make bin/pegjs work when called via a symlink

Similar issue exists on Windows too (they have symlinks since Vista), but I
could not find how to dereference symlinks from batch files, so I did not fix
it. I guess this does not matter much given how little the symlinks are used in
the Windows world.

Closes #1.
