Subject: Keep stdin (file descriptor 0) open in the pager's child process.
X-Git-Tag: 1.1.0~158
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1ccb0019b16b064dfde1e320b7921c82e8409f5b;p=be.git

Keep stdin (file descriptor 0) open in the pager's child process.

This fixes the underlying problem that we worked around in commit
2c9ae15f53aef57d28091b237c193c653c6e80dd.  Now even

  $ echo 'some bug | be --paginate new -

will work instead of raising IOError: [Errno 9] Bad file descriptor.
