Subject: patch 8.0.1210: CTRL-G and CTRL-T are ignored with typeahead
X-Git-Tag: v8.0.1210
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f8e8c0643b1cd97db11912bc4f773e1328a0da02;p=vim

patch 8.0.1210: CTRL-G and CTRL-T are ignored with typeahead

Problem:    When typing a search pattern CTRL-G and CTRL-T are ignored when
            there is typeahead.
Solution:   Don't pass SEARCH_PEEK and don't call char_avail(). (haya14busa,
            closes #2233)
