Subject: patch 8.0.0392: GUI test fails with Athena and Motif
X-Git-Tag: v8.0.0392
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e0c31f6a304496b597a51ce98af419ec815bec74;p=vim

patch 8.0.0392: GUI test fails with Athena and Motif

Problem:    GUI test fails with Athena and Motif.
Solution:   Add test_ignore_error().  Use it to ignore the "failed to create
            input context" error.
