handling of files with CR line ending looks faulty in pdftex

[u-fischer]

• I have read the [MiKTeX Contributing Guidelines]

This is a stripped down example of a problem with a tikz plot.

When inputing a file with pdf

tex with one line of text (e.g. 0.5660 0.6968) which has line ending format CR

\newread\myread
\openin\myread line.txt
[line.txt](https://github.com/MiKTeX/miktex/files/3594729/line.txt)
 %cr line ending
\read \myread to \temp
\read \myread to \temp
\show\temp

\bye

miktex shows

> \temp=macro:
->.

With CRLF and LF ending (and with lualatex and xelatex, and in texlive for all cases) the output is

> \temp=macro:
->\par .

This has been fixed.
