* lisp/progmodes/xref.el (xref-collect-references): Instead of calling `semantic-symref-find-references-by-name', use `semantic-symref-instantiate' and `semantic-symref-perform-search' directly. Ask for `line-and-text' results (bug#23223). (xref-collect-matches): Include the line text in the "hit" structure. (xref--convert-hits): New function, split off from `xref-collect-references' and `xref-collect-matches', to convert "hits" to xref instance list. Create a temporary buffer here, to use it for post-processing all hit lines. (xref--collect-matches): Use a different approach for non-visited files. Insert the line text into the temp buffer, apply the file's major mode the best we can without reading its whole contents, syntax-propertize, and search in the result. (xref--collect-matches-1): Extract, to handle the common logic between two cases. (xref--find-buffer-visiting): New function, a wrapper around `find-buffer-visiting' to amortize its cost. * lisp/cedet/semantic/symref/idutils.el (semantic-symref-idutils--line-re): New constant. (semantic-symref-parse-tool-output-one-line): Support result type `line-and-text'. * lisp/cedet/semantic/symref/grep.el (semantic-symref-grep--line-re) (semantic-symref-parse-tool-output-one-line): Same. * lisp/cedet/semantic/symref/cscope.el (semantic-symref-cscope--line-re) (semantic-symref-parse-tool-output-one-line): Same. * lisp/cedet/semantic/symref/global.el (semantic-symref-global--line-re) (semantic-symref-parse-tool-output-one-line): Same.
