gs a bit confused in /tmp

[hugovk]

scmpuff 0.2.1
git version 2.14.0
macOS Sierra

Clone a repo in /tmp and make a change. First confirm gs is aliased to scmpuff:

[hugo:/tmp/scmpuff] master(+1/-0) ± which gs
gs: aliased to scmpuff_status

Then do a gs:

[hugo:/tmp/scmpuff] master(+1/-0) ± gs
# On branch: master  |  [*] => $e*
#
➤ Changes not staged for commit
#
#       modified:  [1] ../../private/tmp/scmpuff/README.md
#

Compare with a bog standard git status:

[hugo:/tmp/scmpuff] master(+1/-0) ± git status
On branch master
Your branch is up-to-date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

	modified:   README.md

no changes added to commit (use "git add" and/or "git commit -a")
[hugo:/tmp/scmpuff] master(+1/-0) ±

It'd be nice if gs also showed README.md rather than ../../private/tmp/scmpuff/README.md.

Can be reproduced with either of:

/usr/bin/env scmpuff status --filelist
/usr/bin/env scmpuff status

Having a bit of the poke in status.go, the first two Git commands look fine:

[hugo:/tmp/scmpuff] master(+1/-0) ± git status --porcelain
 M README.md
[hugo:/tmp/scmpuff] master(+1/-0) ± git status -z -b
## master...origin/master M README.md%

But perhaps this is the culprit?

[hugo:/tmp/scmpuff] master(+1/-0) 1 ± git rev-parse --show-toplevel
/private/tmp/scmpuff

Hi, this is actually an upstream issue with Go itself that we haven't worked around yet, please see #11 for details.

(Closing this one as duplicate, but appreciate the detailed issue report greatly!)
