find-filename-pattern-encoding-match pathname ef-spec buffer length => new-ef-spec

Arguments

`pathname`⇩	Pathname identifying location of `buffer`.

`buffer`⇩	A buffer whose contents are examined.
`length`⇩	Length (an integer) up to which `buffer` should be examined.

Description

The function find-filename-pattern-encoding-match compares pathname (using pathname-match-p) with elements of *filename-pattern-encoding-matches*.

If a match is found, merges ef-spec with the corresponding external format spec and returns the result as new-ef-spec. Thus it does not override a supplied ef-spec.

buffer and length are ignored.
