works fine

i have made change that now prints name of hgignore file if it should.
matt, please pull it from crew.
also, message is now not so confusing with syntax entry.

The tracebacks are gone, though I feel that the abort message should mention
.hgignore, for clarity. Another thing I noticed on the abort message is that the
pattern line always has a "<syntax>:" prefix added to it - even if it wasn't
there in my .hgignore file.

Else, it seemed to work fine.

Applied. TK, can you retest?

Please apply this little fix (matchfn return None if no patterns are specified).

The attached patch should fix it.

$ hg init
$ echo "*.o" > .hgignore
$ hg status
