master 9e586ac: Signal an end-of-file error upon errors when reading from stdin

[Lars Ingebrigtsen]

branch: master
commit 9e586ac1d1b3bbabbd73a119698df742c0bfa523
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Signal an end-of-file error upon errors when reading from stdin
    
    * src/minibuf.c (read_minibuf_noninteractive): Signal an
    `end-of-file' error when reading from stdin instead of a general
    error (bug#34123).  This makes it easier to write code that
    recovers from this situation.
