It may be just me, but I'd rather see the word "visibility" instead of
"scope" here. I mistook the subject line to indicate that the function is
changed to serve an (at least slightly) different purpose than before,
which is not actually the case.
Another alternative to "visibility" might be to imitate existing commit
messages, such as e4cb659ebdd (diff: export diffstat interface,
2019-11-13), 22184497a36 (factor out refresh_and_write_cache function,
2019-09-11) or ef283b3699f (apply: make parse_git_diff_header public,
2019-07-11).
In addition, as with all such changes, we need to be careful to consider
whether unrelated function names coming in from system headers might
clash. In this case, I think `count_lines()` is a bit too generic, but
will probably not clash. Personally, I would probably have opted for
`count_lines_in_string()`.
Ciao,
Johannes
