#721 closed defect (fixed)

parley seems to drop newlines when piping input from stdin

Description (last modified by Christian Kellermann)

The following program:

(let ((file (read-string)))
  (write file))

is a simple test of read-string. The following does not produce the result I expect:

$ csi test.scm < test.scm
"(let ((file (read-string)))  (write file))\n"

It appears if the newline in the middle of the file is not being preserved? Further, if I remove the "\n" from the test.scm file (please find it attached, I used a program called bvi to remove it, most editors will not let you save a file with a missing final newline), I get:

$ dd if=test.scm bs=1 count=42|csi test.scm
"(let ((file (read-string)))\n"

It seems the final line is being dropped! What is going on here? I expect read-string, when not given a size, to return my input file byte-for-byte?

parley is in use in alan's .csirc, so the problem has been rededicated to parley
