Update: I've had a sleepless night. But I just tried adding an entry and my answer was way off. Please ignore.
Perhaps you can use your mudding client. Parna first tipped me off a feature she used in her client to echo text into an active editor when she was building. I use tt++ so to achieve a similar effect I use the command #textin {/path/file} {delay in seconds} to upload descriptions and such into a text editor. If hedit drops you into a text editor then I don't see why you couldn't do something similar.
I just did a whole cut and paste into the hedit editor... it did it.
I should had thought about it earlier..
It's just that i was used to add new files in circle mud.
IIRC circle mud had files for each "help topic".
TBA mud use something that look like more a database.
