comparison autoload/gutentags/ctags.vim @ 86:7872cc9bbc2d

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Check existing tags file as an opt-in thing for now. Looks like tags files don't all start with the `!_TAG_` magic header so I'm disabling it by default for now.
