pathspec: don't error out on all-exclusionary pathspec patterns

Browse Source 
Instead of erroring out and telling the user that they should add a
positive pattern that covers everything else, just _do_ that.

For commands where we honor the current cwd by default (ie grep, ls-files
etc), we make that default positive pathspec be the current working
directory.  And for commands that default to the whole project (ie diff,
log, etc), the default positive pathspec is the whole project.
