[PATCH] convert: clarify line ending conversion warning

[Alex Henrie <alexhenrie24@gmail.com>]

The warning about converting line endings is extremely confusing. Its
two sentences each use the word "will" without specifying a timeframe,
which makes it sound like both sentences are referring to the same
timeframe. On top of that, it uses the term "original line endings"
without saying whether "original" means LF or CRLF.

Rephrase the warning to be clear that line endings have not been changed
in the working directory but will be changed on the next checkout, and
explicitly say which line endings the file currently has in the working
directory.

Example commands to trigger the warning on Linux:

git config core.autocrlf true
echo 'Hello world!' > hello.txt
git add hello.txt
git commit -m "Add hello.txt"
