Re: fatal output from git-show really wants a terminal

It appears that when outputting a fatal error, git-show will choose

This is by design.

How do I 
redirect the error but still allow stdout to be displayed?

$ git show 12345 2> /dev/null | less

~/git$ mkdir test
~/git$ cd test
~/git/test$ git init
~/git/test$ git show 12345
fatal: ambiguous argument '12345': unknown revision or path not in the
working tree.
Use '--' to separate paths from revisions

You see this through the pager.

~/git/test$ git show 12345 2> /dev/null
fatal: ambiguous argument '12345': unknown revision or path not in the
working tree.
Use '--' to separate paths from revisions

And this went through the pager as well.

~/git/test$ git show 12345 > /dev/null
fatal: ambiguous argument '12345': unknown revision or path not in the
working tree.
Use '--' to separate paths from revisions

This went straight to the terminal.

The pattern is that if stdout is a terminal, the pager is thrown up and both 
stdout and stderr of git show proper are redirected to the pager. If you 
redirect only stderr, then this redirection is actually ignored.
