Subject: getnstr() returns KEY_RESIZE if there was a pending resize event, so loop
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=6def4870fc000b3f92457ea7b2ce64a839cfae17;p=openbsd

getnstr() returns KEY_RESIZE if there was a pending resize event, so loop
until it stops returning that, resetting the cursor position each time.

hint from Gregor Best (gbe (at) ring0.de)
