Subject: setatt: Print meaningful error message.
X-Git-Tag: v0.5.5~27
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=385aab3b349e2d60d2ce863abda57e3a3f2c3afd;ds=sidebyside

setatt: Print meaningful error message.

An attempt to set or unset a non-existing attribute currently results in

	key not found in rbtree

which is a bit cryptic. This commit adds another message that clarifies
what went wrong.
