ffap-dired-wildcards

ffap-dired-wildcards is a variable defined in `ffap.el'.
Its value is

"[*?][^/]*\\'"

Documentation:
A regexp matching filename wildcard characters, or nil.

If `find-file-at-point' gets a filename matching this pattern,
and `ffap-pass-wildcards-to-dired' is nil, it passes it on to
`find-file' with non-nil WILDCARDS argument, which expands
wildcards and visits multiple files. To visit a file whose name
contains wildcard characters you can suppress wildcard expansion
by setting `find-file-wildcards'. If `find-file-at-point' gets a
filename matching this pattern and `ffap-pass-wildcards-to-dired'
is non-nil, it passes it on to `dired'.

If `dired-at-point' gets a filename matching this pattern,
it passes it on to `dired'.

You can customize this variable.
