bug#976: 23.0.60; incorrect code for filesets-get-filelist |

The attached code might help you in fixing this - if not, ignore it. I haven't
tested all of the code that calls `filesets-get-filelist', but the version of
`filesets-get-filelist' attached seems to DTRT, AFAICT.
The problem with the original code, and with the suggestion I sent earlier, is
that `filesets-get-filelist' does not DTRT for type :tree. The original code is
completely broken - does nothing here. In my previously suggested code,
`filesets-get-filelist' does the same thing for type :tree as for type :pattern
- it returns only the files in the directory, not also the files in its
subdirectories.
See attached file for proposed new definition (with new function
filesets-files-under).
