I'm seeing another test failure in Debian's build environment, which
seems to again be related to vim not running attached to a tty. I've
been seeing this since at least 8.1.0549 and the below run is with
8.1.0687.
This line
call feedkeys("ix\<esc>", 'tnix')
in Test_edit_forbidden() gets stuck waiting on input from the user.
The make process that's running the tests has stdin pointed to /dev/null
and stdout/stderr pointed to a pipe.

Vim is spinning in edit() around the call to safe_vgetc(). safe_vgetc()
returns 0x1b (Escape) and cmdchar at the time is 'i'.
The actual loop (at a highlevel, from gdb) is:

Hope that's enough to figure out how to fix this.
