* src/cmp.c (bytes): Use INTMAX_MAX, not -1, for “infinity”. This simplifies the code and is not a value that can be exhausted these days. (main, cmp): Treat very large -n values as “infinity”. * tests/cmp: Test this.

Add --git option to generate output compatible with 'git diff -p'.
|
|
This would behave like 'diff -p', except that it would also generate
|
|
the extended headers 'old mode', 'new mode', 'deleted file mode', and
|
|
'new file mode', and it would quote file names with unusual characters.
|
|
GNU patch already parses this format.
|
|
|
|
Add --include option (opposite of --exclude).
|
|
|
|
Add SEEK_DATA/SEEK_HOLE sparse file optimization to cmp, diff -q, etc.
|
|
|
|
Look into sdiff improvement here:

Propagate stderr from subprocess so that diff3 does
|
|
a better job of explaining _why_:
|
|
> $ diff3 /bin/sh /bin/false /bin/mv
|
|
> diff3: subsidiary program 'diff' failed (exit status 2)
