The existing documentation that I am patching uses the term "worktree
file" which is why I continued to use that wording.

(Unless this is a documentation transition that you want to happen
peicemeal as documentation is updated for other reasons?)

Point taken; I'll use cleanFromFile and smudgeToFile.

Here's a revised version of the documentation that I think takes the other
suggestions onboard. I emphasise that clean and smudge operate as filters,
to contrast better with cleanFromFile and smudgeToFile not operating as
regular stdio filters.

 filter.<driver>.clean::
-       The command which is used to convert the content of a worktree
+       The command which is used as a filter to convert the content of a worktree
        file to a blob upon checkin.  See linkgit:gitattributes[5] for
        details.
 
 filter.<driver>.smudge::
-       The command which is used to convert the content of a blob
+       The command which is used as a filter to convert the content of a blob
        object to a worktree file upon checkout.  See
        linkgit:gitattributes[5] for details.
 
+filter.<driver>.cleanFromFile::
+       Similar to filter.<driver>.clean but the specified command 
+       directly accesses a worktree file on disk, rather than
+       receiving the file content from standard input. 
+       In the command, "%p" is replaced with the name of the file. 
+       Only used when filter.<driver>.clean is also configured.
+       See linkgit:gitattributes[5] for details.
+
+filter.<driver>.smudgeToFile::
+       Similar to filter.<driver>.smudge but the specified command
+       writes the content of a blob directly to a worktree file,
+       rather than to standard output.
+       In the command, "%p" is replaced with the name of the file.
+       Only used when filter.<driver>.smudge is also configured.
+       See linkgit:gitattributes[5] for details.

This could be extended more, but I think this should describe the config
settings concisely and point to the more involved discussion of filter drivers
in gitattributes.
