Subject: patch 9.2.0741: complete_check() does not return TRUE for mapped input
X-Git-Tag: v9.2.0741^0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=37d85f5f1ad336fdc63e949c3b2db8ae7be618e4;p=thirdparty%2Fvim.git

patch 9.2.0741: complete_check() does not return TRUE for mapped input

Problem:  Mapped typed keys didn't interrupt completion in
          complete_check() (Yikai Zhao)
Solution: Also interrupt when in_compl_func and not replaying a register.
          (glepnir)
