I run into this *all* the time: I've been coding for several days,
working on 20-30 files simultaneously, and I need to get back to
the one among these many buffers that contains a particular string
or regex.  The nature of this string or regex varies: most commonly
it's the name of a variable or function, but it could be the regex
'sub [a-z_]+foo[a-z_]+' in a Perl file, or a the string 'cf.' that
I remember using in a comment, or some nifty idiom that matches
'select (.*\]', etc.

I agree that it would be annoying to have the search waste any time
on *info*, *scratch*, etc.  But if the search is restricted to
file-visiting buffers, I think it would be extremely useful.

(I remember using etags years ago, but found it extremely cumbersome,
and useful only in a fraction of the situations for which I needed
this type of global search.)
