Update the `fill-region-as-paragraph-semlf' function to follow the `fill-region-as-paragraph-function' protocol. This allows us to reimplement the `fill-paragraph-semlf' function using `fill-paragraph' and `fill-region-as-paragraph-function'. * lisp/textmodes/fill.el (fill-region-as-paragraph-semlf): Make this function compatible with `fill-region-as-paragraph-function'. Avoid narrowing. (fill-paragraph-semlf): Reimplement using `fill-paragraph' and `fill-region-as-paragraph-function'. * test/lisp/textmodes/fill-tests.el (fill-test-semlf-fill-region): Add test. (fill-test-fill-paragraph-semlf-fill-paragraph-function): Remove test.

* lisp/textmodes/reftex.el (reftex--get-buffer-identifier) (reftex--get-directory, reftex--abbreviate-name) (reftex--get-basename, reftex--get-truename): New helper functions that handle both files and buffer objects. (reftex--remove-buffer-from-master-index): New helper function. (reftex-tie-multifile-symbols): Support non-file buffers, using the above. (reftex-TeX-master-file): Return current buffer when no file. (reftex-access-scan-info): Remove check requiring file buffers. (reftex-access-parse-file, reftex-check-parse-consistency): Skip for non-file buffers. (reftex-select-external-document): Use new helper function. (reftex-locate-file): Return buffer objects directly. (reftex-get-file-buffer-force): Handle buffer objects and special 'buffer:' strings. * lisp/textmodes/reftex-global.el (reftex-create-tags-file): Add error handling for non-file buffers. Leave TAGS unsupported in non-file buffers. (reftex-find-duplicate-labels) (reftex-isearch-switch-to-next-file): Use new helper functions that handle both files and buffer objects. (reftex-isearch-switch-to-next-file): Use equal rather than string= to compare strings/buffers. * lisp/textmodes/reftex-index.el (reftex-display-index) (reftex-index-change-entry): Use new helper functions. (reftex-index-visit-phrases-buffer): Add error handling for non-file buffers. Leave phrases unsupported in non-file buffers. * lisp/textmodes/reftex-parse.el (reftex-do-parse) (reftex-parse-from-file): Add support for non-file buffers. (reftex-all-document-files, reftex-where-am-I) (reftex-notice-new): Use new helper functions. * lisp/textmodes/reftex-ref.el (reftex-label-info-update): Support non-file buffers.

RefTeX historically assumed that the buffers it operates on visit files. To handle non-file buffers: Modify reftex-TeX-master-file so that it returns the buffer object itself (as suggested by Stefan Monnier). Modify each caller to handle buffer objects, aided by some helper functions added to reftex.el. Replace 'string=' by 'equal' in places. Use buffer-base-buffer, where appropriate, to handle indirect buffers (file and non-file). TAGS files and phrases buffers remain unsupported for non-file buffers.
