This is really old school, but a lot of times we have users sending us
copy pasting of codes, and that is the only way to know the version of
the code.

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.

DHGEQZ (QZ iteration failed)
* bug report by Hong Bo Peng Sandgren, on 03-19-2012.
* See link:http://icl.cs.utk.edu/lapack-forum/archives/lapack/msg01257.html[LAPACK Mailing list msg 01257]
I am doing some work with DGGEV. When I check the return msg and the actual code, I found something may be wrong. Here is part of comments in the header of DGGEV.F.
* INFO (output) INTEGER
* = 0: successful exit
* < 0: if INFO = -i, the i-th argument had an illegal value.
* = 1,...,N:
* The QZ iteration failed. No eigenvectors have been
* calculated, but ALPHAR(j), ALPHAI(j), and BETA(j)
* should be correct for j=INFO+1,...,N.
* > N: =N+1: other than QZ iteration failed in DHGEQZ.
* =N+2: error return from DTGEVC.
When INFO = 1...N, there is an error in DHGEQZ (QZ iteration failed). From the code, we can see it jumps to label 110 then set WORK(1) and return.
But in case of we scaled the matrix, we still need to undo scale for the output array ALPHAR, ALPHAI and BETA for those values j=INFO+1,...,N.
In DGEEVX, we can see that it jumps to label 50 in case of DHSEQR failure and then undo scale before return.

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.

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