Subject: cgraph: remove initial '\0' store to new agxbuf
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=db5f46061e2cf56ea132fb4c9b7129a4432bcc59;p=graphviz

cgraph: remove initial '\0' store to new agxbuf

Nothing in the code base relies on this. Callers always use `agxbuse` before
relying on the buffer being NUL terminated.

Gitlab: #2302
