Bug#881654: vim: visible bracket matching broken in configure.ac files

[Ferenc Wágner]

Package: vim
Version: 2:8.0.0197-4+deb9u1
Severity: normal

Dear Maintainer,

Please create /tmp/configure.ac with the following contents:

[AC_MSG_([yes])]

and position the cursor on the first character, the opening bracket.
This highlights the first closing bracket, right after "yes", instead
of the closing bracket at the end of the line.  However, hitting %
correctly jumps to the end of the line.  If I change any character of
AC_MSG_, the issue disappears.

This wrong visual clue is rather annoying, please fix it if possible.
I'd also be interested in a workaround.

Thanks,
Feri.
