Re: [PATCH v2] require_work_tree broken with NONGIT_OK

[Gabriel Filion <lelutin@gmail.com>]

Sourcing git-sh-setup: After having set NONGIT_OK, when calling the
function require_work_tree while outside of a git repository shows a
syntax error.
This is caused by the call to git rev-parse --is-inside-work-tree
printing nothing when it is called outside of a git repository.

Quoting the call removes the syntax error and sending stderr to
/dev/null removes duplicate error messages.
