[bug-diffutils] bug#31105: bug#31105: [PATCH] Restart and reset ANSI escapes on each line for compatibility with less -R

[Dennis Lambe Jr.]

The previous patch had an error in the first hunk for normal.c. I  
forgot to remove an "if" line when I removed the following conditional  
line. Due to its placement before a "for" line that tested the same  
condition, it didn't affect the behavior of the patch, but it was  
unsightly. I've attached an updated patch.

> 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
