Yesterday I found a much better example, and this time even on one of the applications that are really affected by the change...
(svnadmin and svn aren't... see the patch)
See:
$ svndumpfilter --help include
include: Filter out nodes without given prefixes from dumpstream.
usage: svndumpfilter include PATH_PREFIX...
Valid options:
--drop-empty-revs : Remove revisions emptied by filtering.
--drop-all-empty-revs : Remove all empty revisions found in dumpstream
except revision 0.
--renumber-revs : Renumber revisions left after filtering.
--skip-missing-merge-sources : Skip missing merge sources.
--targets ARG : Read additional prefixes, one per line, from
file ARG.
--preserve-revprops : Don't filter revision properties.
--quiet : Do not display filtering statistics.
--pattern : Treat the path prefixes as file glob patterns.
This tells us that
$ svndumpfilter include --pattern "*.txt" < file.dump > newfile.dump
Would evaluate the * as part of the argument parsing, not as part of the filtering.
And as the * is evaluated in svndumpfilter (and not the shell as on *nix), there is no way to escape the *...
