I just realized during the weekend, that this was indeed the reason
for the problems with the erase key on several systems: It was really
a problem on a few terminal types such as Wyse50, where the arrow keys
send single characters, and the left arrow key sends a back space!

This can be work-around without patching the code by the following map
command:

	map key left ^H

which will map the "misinterpreted" left arrow-key back into the erase key.

For some reason (another bug I suppose), the more obvious

	set erase-key left

does not work!
