Typo in help for dgegs and dgegv

[chtobler]

The first line of dgegs.f and dgegv.f has the description

*> \brief DGEEVX computes the eigenvalues and, optionally, the left and/or right eigenvectors for GE matrices

This is particularly confusing on netlib.org, where these are at the top of the list of functions for solving a real eigenvalue problem: http://www.netlib.org/lapack/explore-html/d9/d8e/group__double_g_eeigen.html
