While working on the other patch related to ignore files I came across
inconsistency with git when we do "got st <path to .gitignor'ed file>":

$ got clone ssh://anonymous@got.gameoftrees.org/got.git
$ got checkout -q got.git
$ cd got
$ echo foo > got/.gitignore
$ touch got/foo
$ got st
?  got/.gitignore
$ got st got
?  got/.gitignore

# git doesn't show anything here, 'foo' is in got/.gitignore
$ got st got/foo
?  got/foo

Here is git output:

$ echo foo > got/.gitignore
$ touch got/foo
$ git status --porcelain 
?? got/.gitignore
$ git status --porcelain got
?? got/.gitignore
$ git status --porcelain got/foo
<empty>

# remove .gitignore and check again
$ rm got/.gitignore 
$ git status --porcelain got/foo
?? got/foo

This is a niche case, I haven't researched further.

Xfail test inlined below.

Maybe such behaviour is expected, and we don't want to match git in this?
