[Message part 1 (text/plain, inline)]

Hello!

GNU less can display ANSI-colored text with the -R flag, but this  
support has some limitations. One of them is that if an escape  
sequence starts on one line and ends on a different line, only the  
first line will be colored in less.

As a result, when diff creates colored output with multi-line deletes  
or adds, less will only color the first line.

I've attached a patch to reset ANSI color to the default at the end of  
every line and restart it at the beginning of the next. It patches  
normal and context mode. Side-by-side already worked in my testing.

I hope it's useful to you. Please let me know if there are changes you  
would like made before you can accept it.
