* progmodes/ada-mode.el: Update copyright notice.
Synchronize with GNAT release 3.15a1. Do not attempt to load ada-support, which is only for compatibility with older Emacs versions, and is not needed for Emacs 21. (ada-continuation-indent): New variable. New contextual menu: "List local reference", faster than "List References". (ada-mode): New alignment rules provided by S. Leake. (ada-mode): Add support for which-function-mode. Fix various calls to count-lines, that didn't work correctly when the buffer was narrowed. (ada-get-current-indent): Fix indentation of named parameter lists and nested boolean expressions. (ada-indent-on-previous-lines): Fix indentation of labels. (ada-search-prev-end-stmt): Fix searching of the previous end-statement, specially with regards to nested subprograms. (comment-region advice): Initially disabled, for better compatibility with other modes. (ada-fill-comment-paragraph): Fixed (no longer worked with Emacs 21). * progmodes/ada-xref.el: Update copyright notice. (ada-xref-create-ali): The default is now not to create automatically the ALI files by compiling the unit, since this isn't always reliable and requires an up-to-date project file. (ada-prj-default-comp-cmd): No longer use gcc directly to compile a file, but use gnatmake instead, since this gives access to the GNAT project files. (ada-xref-search-with-egrep): New variable, suggested by P. Waroquiers. (ada-load-project-hook): New variable, for support of GNAT project files. (ada-update-project-menu): Fix the detection of the project file name. (ada-add-keymap): Change key binding for ada-find-file, that conflicted with another binding in ada-mode.el. (ada-add-menu): New menu "List Local References", to list the reference to the entity only in the current file, instead of looking in the whole project. Much faster. (ada-find-references): New parameters arg and local-only. (ada-find-any-references): New parameters local-only and append. (ada-goto-declaration): Fix handling of predefined entities in xref. (ada-get-all-references): Updated to the new xref format in GNAT 3.15, still compatible with GNAT 3.14 of course. Fix various calls to count-lines, that didn't work correctly when the buffer was narrowed.
