Subject: [PATCH] minibar: word-for-word replacements: use concrete syntax for
 replacement words when possible

Instead of showing the name of a function in the abstract syntax, linearize it
and show the result. For functions with argument, e.g. That : Kind -> Item,
the function is applied to the right number of placeholder arguments: 'That ?'.
If the linearization fails, the name of the function is shown anyway.
