This is more in keeping with the UNIX convention of no output on success,
and is also the way Stow v1.x behaved. Thanks to Adam Sampson for the suggestion.
I'm guessing it was added due to a misunderstanding of how shell
quoting works. When you invoke
stow --ignore=".#.*" ...
the shell strips out the quotes before the Perl process ever sees them.
I can't imagine any sensible scenario in which you would need to invoke
stow --ignore='"foo"'
but if the user has a filename containing quotes at the beginning and
end, they can now choose to ignore it (prior to this patch, they couldn't).
