New Revision: 346744
URL: https://svnweb.freebsd.org/changeset/base/346744
Log:
Restore the line width in VGLEnd(). The line width may be changed by
VGLSetVScreenSize(), but is not restored by mode switches to at least
standard text mode, so must be restored explicitly. Standard text mode
displayed blanks when the line width was doubled.
