comparison autoload/gutentags/ctags.vim @ 168:e59321cbaff7

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use scope-local functions This avoids overriding local cwd settings, as vim allows `lcd` for window-local working directory and neovim supports additionally `tcd` for tab-local working directory.
