Remove unused unexported variable.

creachadair · creachadair · commit a4ab5868b489 · 2022-10-29T10:21:04.000-07:00
The eraseUnderCursor variable is unused, it came in with the import of the x/crypto/ssh/terminal package at d7a7210 but is not referenced here. When this package is vendored, the unused unexported name trips warnings from tools like staticcheck.
