X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=259dfd20b9f835e701edef569795198ff7cf68cb;p=emacs.git

Use three-argument form for out-of-range errors.

This provides more debugging hints for callers.

* src/emacs-module.c (module_copy_string_contents): Use three-argument
form of args-out-of-range.
