Package: man-db
Version: 2.7.2-1
Severity: normal
Current "man -a" uses /dev/tty unconditionally. This means no way to use
for scripting usage, or such.
For example, emacs can view all manpages via (setq Man-switches "-a").
With this configuration, emacs does
man -a <name> | post-process
But current man version asks via /dev/tty in background, and bother emacs.
Also simple example is,
$ man -a <name> | less
Older versions can show all manpages as contiguous file. Current version
ask to user via /dev/tty in background from man command, totally useless.
The following patch restores the behavior of older version.
Thanks.
