Add the #'apply-partially API, as used by GNU. lisp/ChangeLog addition: 2011-08-12 Aidan Kehoe <kehoea@parhasard.net> * cl-macs.el: * cl-macs.el (apply-partially): New compiler macro. * subr.el: * subr.el (apply-partially): New. Sync this function's API and docstring from GNU. The implementation is mine and trivial; the compiler macro in cl-macs.el ensures that partially-applied functions in compiled code are also compiled. tests/ChangeLog addition: 2011-08-12 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Trivial tests of #'apply-partially, just added to subr.el.

### Commentary:

## Extract all the @foo@ configuration symbols from ../configure
## to make them available to elisp later (see util/config.el)
## Primarily useful for creating ridiculously verbose bug reports.
##
## See lisp/config.el, ../configure.in,
## and the Autoconf documentation on AC_OUTPUT, for more details.
##
## This script needs only to be run occasionally (before a Net release)
## by an XEmacs Maintainer (consider yourself so blessed, if you are
## actually reading this commentary).
