Just an idea: Seems that currently \= matches the position at the
beginning of the file names!  Could we maybe just guarantee and document
that?

If \= works reliably, we may also transform a leading \` in the regexp
into \=.  ^ is not so important in my eyes, it's easier to type than \`,
but the semantics of "beginning of line" is not as clear in this context
as "beginning of the object searched". If \= and \` would work, I would
be very happy.

Michael.
