This commit changes the processing principle of the -X/-XX modes from 1-pass to 2-pass. A separate width measurement stage has been added, so that the real maximum widths can be measured and used for correct indentation. The firstmapping variable now has a new value (2) used for the width measurement stage (1st pass). The printing is disabled in this stage. The file position is reset to the beginning of the file once the end of file is reached and the printing stage (2nd pass) begins. It's questionable if this approach is sensitive to Read-after-Write race conditions. Anyway, this feature is a good candidate for a complete redesign in the future. Additionally this commit introduces a final cleaning of the list used for the evaluation of totals in the -X/-XX modes.
COMPATIBILITY
This code is intended for use with Linux 2.6.xx, 3.x and
hopefully all future kernels.

HOW TO CONTRIBUTE
See Documentation/BUGS file.
PACKAGING
If you are a downstream maintainer (packager) for a Linux
distribution, please avoid causing troubles. This section
applies to you.
Avoid maintaining distribution specific patches. Send your
patches to upstream, where they are at least reviewed, if not
included.
Please forward bug reports. If your bug database is public and
busy enough to bother with, please make this known. Follow
Debian's lead in making the bug database easy to comment on via
email without need for an account.
For normal packages, ensure that you do not add debugging flags
to the CFLAGS variable.
