{- completion-logic:

due to shortcomings of the Shellac interface concerning completion

(no context-sensitive completion possible!), we implement the following

completion logic using the AnEvenState:

* When a filename argument is completed we remember the completion in the

state-field stCompletionState.

* When a command using filename arguments is executed we clear the

stCompletionState field

* In the specname completion function we use the stCompletionState field to

read eventually the specfile and extract the possible specnames
