I'd like to see some kind of keyword on each line, so that we could extend the command set by adding new keywords. As this stands, I fear we'd end up using random punctuation characters in place of [+-], which seems pretty horrid from a readability standpoint.
I think that this file format should be designed with an eye to allowing every, or at least most, pg_dump options to be written in the file rather than on the command line. I don't say we have to *implement* that right now; but if the format spec is incapable of being extended to meet requests like that one, I think we'll regret it. This line of thought suggests that the initial commands ought to match the existing include/exclude switches, at least approximately.
Hence I suggest
include table PATTERN exclude table PATTERN
which ends up being the above but with words not [+-].
Here is an updated implementation of filter's file, that implements syntax proposed by you.
