[Adam Heath <address@hidden>] Bug#98991: AC_COPYRIGHT when used in aclocal.m4 generates incorrect shell code

[Ben Pfaff]

The following bug was reported against the Debian GNU/Linux
package for Autoconf version 2.50.  I reproduced it and didn't
see any obvious mistakes in the syntax, so I'm passing it on
upstream.

Thanks,

Ben.

If I have AC_COPYRIGHT in configure.in, then it works correctly.  However, if
it is part of aclocal.m4(I run aclocal -I foodir), then it fails.  This goes
against the reason for the macro, as I may include some macro file, from
another source, that has some kind of copyright, but it won't be included
correctly into the configure script.
