Subject: Fix byte-compilation warnings in semantic/symref/grep
X-Git-Tag: emacs-26.0.90~390
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9da8d600b8453925d92b31ba98548480ad1e5c73;p=emacs.git

Fix byte-compilation warnings in semantic/symref/grep

* lisp/cedet/semantic/symref/grep.el (greppattern): Remove.
(grepflags): Rename to semantic-symref-grep-flags.
(semantic-symref-grep-expand-keywords): Update accordingly.
(semantic-symref-grep-use-template): Remove the last two
arguments to make sure they don't shadow the (not renamed)
global variables.
(semantic-symref-perform-search)
(semantic-symref-parse-tool-output-one-line): Use slot names
instead of keywords, like the byte-compiler wants us to.
