Subject: * src/bytecode.c (exec_byte_code): Remove superfluous condition
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=58e5b9223b2efd70016c4777203ee26a00c10126;p=emacs.git

* src/bytecode.c (exec_byte_code): Remove superfluous condition

Bytecode should never be able to set anything to Qunbound because that
value is not accessible from Lisp.  Found by Pip Cet.

(cherry picked from commit ebdad09c5a0a822acb52ec58b3319d77d156f0ce)
