From: Phillip Wood <phillip.wood@xxxxxxxxxxxxx>
After the user has edited a hunk the number of lines in the pre- and
post- image lines is recounted the hunk header can be updated before
passing the hunk to "git apply". The recounting code correctly handles
empty context lines where the leading ' ' is omitted by treating '\n'
and '\r' as context lines.
Update this code to use normalize_marker() so that the handling of empty
context lines is consistent with the rest of the hunk parsing
code. There is a small change in behavior as normalize_marker() only
treats "\r\n" as an empty context line rather than any line starting
with '\r'. This should not matter in practice as Macs have used Unix
line endings since MacOs 10 was released in 2001 and if it transpires
that someone is still using an earlier version of MacOs where lines end
with '\r' then we will need to change the handling of '\r' in
normalize_marker() anyway.
