A space is added if only one match is found, but we avoid adding
redundant spaces.
We complete "empty" tokens, i.e. when the cursor is at the start of the
line or in front of a space. For example:
mkdir test
cd test
touch test
chmod +x test
export PATH=/home/anon/test
Now if you press tab, or space and then tab, you will get "test". Notice
that you also get a space.
Completion is now done relative to the cursor. You can enter two words
and then go back and complete the first one.
