git ls-files -o seems to ignore .gitignore

-----BEGIN PGP SIGNED MESSAGE-----

I'm having an issue in that 'git ls-files -o' seems to ignore
[parts of] .gitignore whereas other commands, such as 'git status'
seem fine.

Here is an example:

richard@omnis:/home/richard/src/pkgsrc$ export LANG=C 
richard@omnis:/home/richard/src/pkgsrc$ git --version git version
2.1.2 richard@omnis:/home/richard/src/pkgsrc$ cat .gitignore 
pkgchk*.conf* .#* README*.html 
richard@omnis:/home/richard/src/pkgsrc$ git status On branch dev

It took 6.82 seconds to enumerate untracked files. 'status -uno' 
may speed it up, but you have to be careful not to forget to add 
new files yourself (see 'git help status'). nothing to commit,
working directory clean richard@omnis:/home/richard/src/pkgsrc$ git
ls-files -o |grep -c README 12393

Known issue?

This is, as far as I am aware, by design. If you want to apply the
standard ignore rules to the output of ls-files -o then you can use the
--exclude-standard option.
