environment.

itself. Use `run-hooks' to take buffer-local values into account.
This means it’s no longer possible to warn which hook function had an
error.

a list.
(yas-exception): Add `error-message' property.
(yas-verify-value): Just use plain format since the new `error-message'
property for `yas-exception' will add the right prefix.
* yasnippet.el (yas-good-grace): Add support for `inline' and `hooks' options.
(yas--eval-for-string): Renamed from `yas--eval-lisp'. Errors are
passed straight through (no rethrow) when `yas-good-grace' is nil.

`yas--safely-run-hook'.

mirrors are updated.
(yas--mirror-update-display): Don't indent here.
* yasnippet-tests.el (single-line-multi-mirror-indentation-2): New test.
org-mode implements the "native" tab for source blocks by copying the
source block text into a temporary buffer, calling the command bound to
<tab>, and then copying back the result. To preserve snippets in this
scenario, when the temp buffer is killed we record the relative
locations of the snippet's markers and overlays and then put them into
place in the post command handler.
* yasnippet-tests.el (yas-org-native-tab-in-source-block): New test.
* yasnippet.el (yas--snippets-to-move): New variable.
(yas--prepare-snippets-for-move, yas--finish-moving-snippets): New

Emacs' builtin keybinding lookup code will do the searching instead.

method.

testing binding.

(yas--on-field-overlay-modification):
(yas-expand-snippet, yas--snippet-create): Use it.
While officially it was an "internal" function, there were at least 2
other packages using it.
