I finally upgraded from XP to Win7 so I'm now able to use some of these GitHub tools to apply changes to the account. I am however not familiar with all the settings so by creating the Asmc account I just went with the default configuration.
As it turns out the default seems to be to translate all CR/LF pair to LF, so all the text files was stripped in the .ZIP file when I downloaded from Windows.
I applied the following changes to the .gitattributes file:
# Auto detect text files and perform LF normalization
#* text=auto
* text eol=crlf
This seems to work not..
The solution appear to be declaring each file type manually:
# Auto detect text files and perform LF normalization
* text=auto
# Declare files that will always have CRLF line endings on checkout.
*.c text eol=crlf
*.h text eol=crlf
*.inc text eol=crlf
*.ini text eol=crlf
*.asm text eol=crlf
