[PATCH v3 10/12] sub-process: do not use strbuf_split*()

From: Junio C Hamano <gitster@pobox.com>
Date: Aug 3, 2025, 06:53 UTC
Message-ID: <20250803065304.3325286-11-gitster@pobox.com>
In-Reply-To: <20250803065304.3325286-1-gitster@pobox.com>

The code to read status from subprocess reads one packet line and tries to find "status=<foo>". It is way overkill to split the line into an array of two strbufs to extract <foo>.
