fix: remove trailing carriage return from --version output for cross-platform compatibility

[shackdown]

What this PR does?

This PR updates the edit --version output to use platform-specific line endings:

• On Windows: \r\n (carriage return + newline)
• On Unix-like systems (Linux, macOS): \n only

Previously, the output always used \r\n, which introduced a trailing carriage return (\r) on Unix platforms. This caused subtle issues in shell scripts, such as incorrect string length and version comparison failures.

Before the fix:

ABC=$(./edit --version) ; echo ${#ABC}
# 19 (includes trailing \r)

After the fix:

ABC=$(./edit --version) ; echo ${#ABC}
# 18 (correct length)

closes: #527

That's not what's going on here and not the right way to fix this. CRLF line endings are needed on UNIX too, if ONLCR is not set. This is the case when we switch into raw mode. The switch occurs before we print the version message.

So, what we need to do is delay the raw mode switch until after we parsed all arguments, etc., and before we do anything else. Then we can print the version message with LF only on both Windows and UNIX.
