* .travis.yml (install): Set warnings to (not cl-functions) if cl-lib
needs to be downloaded. Since the downloaded cl-lib just aliases cl.el
functions, trying to use cl- prefixed functions would cause compile
warnings otherwise.
* Rakefile: Pass environment variable `warnings' as
`byte-compile-warnings' value when compiling.
* .travis.yml: Don't use sudo, submodules.
(env): Test with additional Emacs versions.
(install): Get Emacs binaries from
https://github.com/npostavs/emacs-travis/releases. Download ert and
cl-lib if needed.
(script): Split compilation and testing into separate steps.
* Rakefile: Use batch-byte-compile. Treat compilation warnings as
errors.
* .travis.yml: new file
* README.mdown: Add Travis CI badge.
* Rakefile: use ert-run-tests-batch-and-exit.
* yasnippet-tests.el (example-for-issue-404-external-emacs): Use
`yas-with-snippet-dirs' to not depend on bundled snippets.
(yas--call-with-temporary-redefinitions): Use `cl-labels' since no
cl-flet in emacs-24.3's cl-lib.el.
(loading-with-cyclic-parenthood): prog-mode doesn't exist in emacs
24.3.
(yas-batch-run-tests): remove it.
* yasnippet.el (require): require cl-lib during byte-compilation
and load.
