Subject: [PATCH v4 04/12] pkt-line: add options argument to read_packetized_to_strbuf()

From: "Johannes Schindelin via GitGitGadget" <[email-masked]>
Date: Wed, 17 Feb 2021 21:48:40 +0000

From: Johannes Schindelin <[email-masked]>

Update the calling sequence of `read_packetized_to_strbuf()` to take
an options argument and not assume a fixed set of options.  Update the
only existing caller accordingly to explicitly pass the
formerly-assumed flags.

The `read_packetized_to_strbuf()` function calls `packet_read()` with
a fixed set of assumed options (`PACKET_READ_GENTLE_ON_EOF`).  This
assumption has been fine for the single existing caller
`apply_multi_file_filter()` in `convert.c`.

In a later commit we would like to add other callers to
`read_packetized_to_strbuf()` that need a different set of options.
