Subject: write output of long chain test to /dev/null
X-Git-Tag: 2.44.1~31^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=632fe0bd1cfc6a4f636db4f85206aff6720bdc6b;p=graphviz

write output of long chain test to /dev/null

This avoids generating a large file in the source tree that we don't need. In my
runs in a Linux VM, this also significantly speeds up the test suite.
Closes #1720.
