This adds an -s|--silent-ignore option to git-add, which causes
ignored files that were specified explicitly on the command line to be
silently ignored, rather than abandoning the command. I found this
useful for scenarios where you want to feed the file list into git add
via find or other external commands (`find .... | xargs git add'),
which you wouldn't want to carefully tune so they don't output any
ignored files. git ls-files doesn't have find's filtering
capabilities, and using it in place of find would kind of violate "one
job one tool" anyway. I'm not really a git guru, so maybe I'm missing
something, and I'm unsure how useful this new option is for a general
audience. OTOH the patch is trivial. Check it out.

The update applies on top of "master" (261b5119).

I am personally not sympathetic to the reasoning stated in the
proposed commit log message above your signed-off-by line; the
change is not justified at all.

But I'll comment on the code changes anyway.

I'd prefer not to see a new option whose worth hasn't been proven in
the field to squat on any short-and-sweet single letter option
name and would suggest replacing that 's' with 0, at least for now.

The second variant is unwarranted.  We may have a variable or two
that are accepted with '-' or '_' in their names, but they are
backward compatibility measures, only to cover previous mistakes
that named them in these letters in the first place.

Another option would be a -k (--keep-going) that would ignore the files,
but not silently. "git mv" has such an option already.

Can you explain this kind of thing in the actual commit log message
when you reroll (if you will do so)?

I also cannot help but find that `scenario` an artificially made-up
one.  The description did not feel convincing enough, even if it
were in the proposed commit log message, to justify such an option.

A few questions.

 - What were the kind of patterns useful in the above `find` in your
   real life example?

 - The use of `find` means giving pathspecs from the command line,
   e.g. "git add foo/ \*.rb", wouldn't have been sufficient. Are
   there something we could improve this in more direct way?

 - Why was it too cumbersome to add the idiomatic

	\( -name '*.o' -o -name '*~' \) -prune -o

   or something like that in front of whatever patterns were used?

 - Perhaps a filter that takes a list of paths and emits only the
   ignored paths (or only the unignored paths) would be a more
   generic approach?  You could feed the output from `find` to such
   a filter, and then drive not just "git add" but other commands
   that take paths if you solved it that way.
