Re: Isearch in dired

["Richard M. Stallman" <rms@gnu.org>]

    I think the most convenient default behavior would be context-dependent,
    i.e. match only file names when point is on the file name column - where
    point stays most of the time: after opening a dired buffer and through
    dired operations including navigation.  So it would be natural to do the
    same for isearch - never let point leave the file name column.

    To search of the entire buffer, the user can move point outside the
    file name column.  Since this need is very rare, there's no hassle.

That sounds quite convenient.  If the prompt says "File name Isearch"
when appropriate, people will understand what's going on.
