You don't have to have a special file.  For me, this simple recipe did
the trick:

1. emacs -Q
2. M-x load-file RET visual-file-name-abbrev.el RET
3. M-x rgrep RET (defsubst RET *.el RET ~/Repos/el/emacs
4. In the *grep* buffer: M-x visual-file-name-abbrev-mode

As a result, the file names are indeed abbreviated but when I move up
and down using C-n/C-p, I'd expect the file name under point to be
displayed normally (so not the 'display spec but the normal text).  With
emacs -Q, the problem is even worse than with my usual config.  It seems
the conditional display spec is almost never tested, except when the
window is scrolled, but then usually after scrolling point is not on the
file name anymore which is now shown unabbreviated.
