diff parser: match the header order of hg diff --git patches The output might look like: diff --git a/A b/B old mode 100644 new mode 100755 rename from A rename to B --- a/A +++ b/B Such files were shown as 'modified binary file chmod 100644 => 100755' without diff. Now the chmod and diff will be shown ... but still not the rename. Correct parsing of headers do require a better parser - one do not just use a regexp.
