Yes, in readch():

Sure, because reading from stdin won't work, if we
use "more" in a pipeline:
ls -lR /dev | more
Since terminals typically where setup up by opening
filedescriptor 0 (stdin) in O_RDWR mode, and using
dup(2) twice to clone fd 0 to 1 (stdout) and 2(stderr),
"more" can in fact use a read on stderr to get terminal
input.
Standards also describe this feature
("The stderr stream is expected to be open for reading and writing."),
e.g. here:
