Abbreviations containing "^" are handled wrong (Glulx)

[erkyrath]

When testing my Advent-abbrev.inf source file, which contains the line

Abbreviate ".^^";

...the help text comes out with literal "^" characters:

I know of places, actions, and things. You can guide me using commands that are complete sentences. To move, try commands like "enter," "east," "west," "north," "south," "up," "down," "enter building," "climb pole," etc.^^I know about a few special objects, like a black rod hidden in the cave. ...

I haven't checked to see how far back this bug goes. Might have always been this way.

(Test other escape characters: ~, @@64...)

Goes back to 6.31 at least. So yeah, it's always been this way (in Glulx). Shows how little people use -e in Glulx, I guess.
