Re: Update \(en in copyright notices

[Bruno Haible]

Hi Paul,

When I see this ChangeLog entry:

        Update \(en in copyright notices
        * build-aux/update-copyright (ndash_re): New var, matching \(en too.
        (stmt_remainder_re, stmt): Use it.
        (stmt): Match year in constructs like "\(en2023".
        (ndash): Now \(en in man pages.

I wonder: Where are the unit tests? So I'm adding 4 unit tests (see below):

- $TMP.1 for a man page that has the copyright notice in comments (such as
  coreutils/man/du.x).
- $TMP.2 for a man page that prints the copyright notice in a '.SH COPYRIGHT'
  section (such as coreutils/man/expr.1).
- $TMP.3 likewise but where the author used \(en.
- $TMP.4 likewise but where the update-copyright should recognize the man page
  syntax from the use of \(co and should therefore insert \(en instead of -.

But when I run the unit tests
  $ rm -rf testdir1; ./gnulib-tool --create-testdir --dir=testdir1 
--single-configure --symlink update-copyright
  $ cd testdir1
  $ ./configure
  $ make check

I get a test failure already in the previously existing test cases:

It looks like the new code is inserting \(en in TeXinfo source files.
