Subject: [PATCH v4 7/8] pretty: refactor `format_sanitized_subject()`
Date: Fri, 21 Aug 2020 21:41:49 +0000	[thread overview]
Message-ID: <6105046d96223bda40ab0f0177e4f0281376ba53.1598046110.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.684.v4.git.1598046110.gitgitgadget@gmail.com>

From: Hariom Verma <hariom18599@gmail.com>

The function 'format_sanitized_subject()' is responsible for
sanitized subject line in pretty.c
e.g.
the subject line
the-sanitized-subject-line

It would be a nice enhancement to `subject` atom to have the
same feature. So in the later commits, we plan to add this feature
to ref-filter.

Refactor `format_sanitized_subject()`, so it can be reused in
ref-filter.c for adding new modifier `sanitize` to "subject" atom.

Currently, the loop inside `format_sanitized_subject()` runs
until `\n` is found. But now, we stored the first occurrence
of `\n` in a variable `eol` and passed it in
`format_sanitized_subject()`. And the loop runs upto `eol`.
