There is repo[None].files(), which lists all the files that have changed, but it does not respect command line arguments. When someone appends file arguments to the hg call (e.g. hg commit -m "lorem" only_this_file.txt) I found no possibility to respect this "filter". The files method always returns all files.

I use:

[hooks]
pretxncommit.blacklist = /usr/local/bin/hgblacklist
pretxncommit.sanity = /usr/local/bin/hgsanity

to do various checks.  If the hook raises any kind of error the commit 
is rolled back.
