Subject: patch 8.0.1417: test doesn't search for a sentence
X-Git-Tag: v8.0.1417
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1bd999f982e783219a06e6c8f219df1d53ac7e77;p=vim

patch 8.0.1417: test doesn't search for a sentence

Problem:    Test doesn't search for a sentence. Still fails when searching for
            start of sentence. (Dominique Pelle)
Solution:   Add paren. Check for MAXCOL in dec().
