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.

Followed recommendation, use the existing sorting code.
Report sent to LAPACK mailing list on June 26th 2012
From Joseph:
> There appears to be an inconsistency and possible bug in the dstemr
> implementation. When calculating the eigenvalues of a matrix, the
> returned eigenvalues are supposed to be returned in ascending order.
> Although this appears to be the case for N >= 3, it does not appear to
> be the case for N=2. I believe this happens because the dstemr routine
> has special cases for N=0,1, and 2, which immediately return after their
> computation. Because these cases return immediately, they do not call
> the sorting routines around line 723 (in LAPACK version 3.4.1). As
> such, a simple fix would be to have the N=2 case call this sorting code
> rather than returning.
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.

Modify the formatting of the comments.
Replace Note and Notes section by Further Details
This allow the manpages to be generated corectly.

Fix non-short-circuited tests in ILAxL{C,R}.
Fortran doesn't short-circuit logical operators, so the check that the leading
dimension /= 0 may not prevent indexing into a 0-length array.
