[PATCH 6/9] notes: do not use strbuf_split*()

From
Junio C Hamano <gitster@pobox.com>
Date
Jul 31, 2025, 07:41 UTC
Message-ID
<20250731074154.2835370-7-gitster@pobox.com>
In-Reply-To
<20250731074154.2835370-1-gitster@pobox.com>

When reading the copy instruction from the standard input, the program reads a line, splits it into tokens at whitespace, and trims each of the tokens before using. We no longer need to use strbuf just to be able to trimming, as string_list_split*() family now can trim while splitting a string.

Retire the use of strbuf_split().

Note that this loop is a bit sloppy in that it ensures at least there are two tokens on each line, but ignores if there are extra tokens on the line. Tightening it is outside the scope of this series.
