No, it's not the inversion of the pattern, but the slash (if it is not at
the end) that makes the pattern non-recursive.

If you have only the directory vendor/ with no further interesting
subdirectories, then you can use my first suggestion. But if you have your
*.exe and *.o distributed over several directories of different depths
below vendor/, then it might be easier to have a separate
vendor/.gitignore with recursive patterns (i.e. that do not contain a slash).

After reading the documentation, I don't know, and I won't try now ;-)
