Let's not go there.

I was reviewing the list of plumbing in Documentation/git.txt
last night, and I think ls-files is the only command that user
may still want to use from the command line every day.

I originally thought that it would only be after a conflicted
merge, always with -u option, but some people seem to find that
"ls-files --others" and friends are useful (I never use that
myself) and if so what it does really in the realm of Porcelain.

I haven't formed a firm opinion on this yet, but possibilities
are:

 * we reclassify ls-files as a Porcelain-ish (but do not change
   its UI nor defaults at all); we might want to give a shorter
   alias to the command, though, if we go this route.

 * we give '--list' option to 'git show' and in such a case,
   lack of objects does not default to HEAD -- when no object is
   given it internally diverts to cmd_ls_files() instead;

 * we add 'git ls' command to give Porcelain-ish access to
   ls-tree and ls-files.
