Many data structures had wrong spacing when outputting with operator<<
for the data structure. For example, see the missing space between
content and alphabet in string::LinearString.

Let's fix that, it bothered me for quite a long time.

Extended tree patterns feature node wildcards representing any label in the
match of the pattern in the corresponding node
