Yes, I'm more worried about the implication that anything distributed will
be assumed to be robust for any usage. In the usage for which difflog.pl
is supplied, security is not an issue since you're diffing two publicly
available logs. People need to be discouraged from thinking the same
script will work as a heavy-duty tool for logs that might need more
Maybe we should simply leave it out of the distribution (but leave it in
the archive), since it's essentially no use unless you have a CVS tree. It
might be worth adding a new list in .distfiles to indicate this...
It looks like the "distfiles" stuff isn't yet documented, as far as I can

+Distribution of files
+zsh is distributed in two parts: a "src" distribution containing all
+the source files (roughly, but not exactly, corresponding to the CVS
+tree), and a "doc" distribution containing some pre-built files from
+the documentation directory. All the files in the "doc" distribution
+may be generated from files in the "src" distribution with appropriate
+freely available tools.
+To indicate which files should be distributed, each directory in the CVS
+tree includes a file .distfiles that sets any number of a set of Bourne
+shell (scalar) parameters. The value of the parameter is expanded as a
+set of standard command line arguments. Basic globbing is allowed in the
+The following parameters are currently used:
+- DISTFILES_SRC is a list of files from the directory for the "src"
+- DISTFILES_DOC is a list of files from the directory for the "doc"
+- DISTFILES_NOT is a list of files that will not be included in a
+ distribution, but that need to be present in the CVS tree. This
+ variable is not used by the zsh build process and is present for
+ the convenience of external checks.
