Problem:

Edition of Specification (Year): 2003

Defect code :  2. Omission

Diff is utility that compares two files and outputs the difference, it is 
commonly used in software development to share updated source code.

POSIX mentions 3 formats that the difference can be described in, these formats 
are specified using the -e (ed format), -f (modified ed) and -c (context diff).

There is another format which is similar to your context diff, it is called a 
unified diff, for an implementation please refer to the GNU diff program.

Ive been an active member of the open source computing for a number of years 
and i would estimate unified diff is used in over 95% of diff's i have seen.

I feel the omision of the default format of diff reflects very poorly on what 
otherwise appears to be a fairly accurate standard.



Action:

I recommend you incude the unified diff format, you may also want to make some 
of the other formats as obsolete or depreciated.
