Subject: [PATCH] reject empty xresources (#340)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

currently, in case of an empty xresources we would fail to init:

	nsxiv: Error allocating color ''

instead, just reject empty value and use the fallback.

Closes: https://codeberg.org/nsxiv/nsxiv/issues/339
