Subject: [PATCH] wrap-for-bin: do not export an empty GIT_TEMPLATE_DIR
Message-ID: <7vaauqmcpd.fsf@alter.siamese.dyndns.org>
URL: https://gitlist.dev/e/7vaauqmcpd.fsf%40alter.siamese.dyndns.org

```
With bash on some platforms (e.g. FreeBSD 8.0), exporting an unset
variable does not "unexport" it.  The called process gets an empty
string from getenv(3) instead of NULL.
