920185c69a cmp: remove history comment. it is more natural to keep it in source control
The comment was:

* Mar 16, 2003      Manuel Novoa III   (mjn3@codepoet.org)
*
* Original version majorly reworked for SUSv3 compliance, bug fixes, and
* size optimizations.  Changes include:
* 1) Now correctly distinguishes between errors and actual file differences.
* 2) Proper handling of '-' args.
* 3) Actual error checking of i/o.
* 4) Accept SUSv3 -l option.  Note that we use the slightly nicer gnu format
*    in the '-l' case.

Subject: [PATCH] diff: correct handling of labels

This fixes an issue where diff would apply labels to files in the
inverse order, when using -L or --label.
This fixes it in order to be compatible with gnu diff.
It also makes it not an error to specify more than one label.
The behavior for such cases is that they override the label for the new
file.
