This is mostly a long term maintenance improvement.
Many coding styles require elimination of trailing whitespace, and
many editors and source code management configurations automatically
gobble up whitespace. When these tools gobble up whitespace, it
complicates reviewing the meaningful code changes.
By removing whitespace on one patch, it makes future
code reviews much easier.

Issue: ?TGSEN use of array SELECT on workspace query may SEGV
Solution: Skip use of array SELECT on workspace query
Make sense...

Use \par instead of \details for section.
add a Contributors Section and a Reference Section.
Remove (some) verbatim section when not needed.
Those changes have been done by hand so I am not sure I manage to catch them all.

Now each routine should have the correct list of arguments.
This allowed to detect and fix problems in parameter description of many routines.

conjugate transpose (**H)
Corresponds to bug0024
Please take a look and let me know if you find some old notation of transpose.
I am going to close bug0024.

follow-up commit ... ]]
Bug report sent by Alexander V. Kobotov (from Intel) on Mon, 6 Apr 2009 to "lapack@cs.utk.edu".
"(d/s)tgsen.f: iwork(1) always referenced: line 455: iwork( 1 ) = LIWMIN,
documentation says that if IJOB=0 it shouldn't, so NULL pointer causes a
sigfault."
(There is indeed the same problem for the WORK array and the IWORK array in the
complex routines.)
I have changed the header of the routines ctgsen.f, dtgsen.f, stgsen.f, and
ztgsen.f. A Fortran array needs to be of size at least 1. So IWORK is of size
at least 1. It was indeed written in the header of the routine:
"IWORK (workspace/output) INTEGER array, dimension (MAX(1,LIWORK))"
So since IWORK is of size at least 1, there is no reason not to reference it.
When there is a workspace query with IJOB.EQ.0, WORK(1) and IWORK(1) are both
set to 1.

Those are just cosmetic changes to update version number and various other minor change.
