    As the author of igrep.el, I respectfully disagree.  By separating the
    arguments, you can provide access to independent completion (primarily
    for file names) and history (primarily for search strings/expressions).

I find it less convenient.  I never use completion in file name
arguments to grep, because they are normally brief and have wildcards.
