"cat ~/.ssh/id_rsa.pub" will get different content in windTerm gitbash and native gitbash.

Hi ,

I find an issue , my following operations are in window10 os.

1. in windTerm gitbash ， run "cat ~/.ssh/id_rsa.pub" and copy it to VSCode, I see it has four lines.
2. in native gitbash , run "cat ~/.ssh/id_rsa.pub" and copy it to VSCode, see it has only one line.


in fact , If I open ~/.ssh/id_rsa.pub in VSCode , I see it has only one line.

Reproduce on Windows 10 by running `cat ~/.ssh/id_rsa.pub` in WindTerm Git Bash and native Git Bash, then compare both results with the file opened in VSCode. Trace how terminal output handles line breaks and determine the expected behavior; done means the discrepancy is explained and the reported output is corrected or documented.
