issue file : white and lightgray don't work, plus there are some mistakes in agetty's man page

[sukolyn]

Hi,

I put some colors in /etc/issue, but I cannot get white, neither lightgray

$ LC_ALL=C agetty -V
agetty: invalid option -- 'V'
Try 'agetty --help' for more information.

-V is in the man page, but not in the --help.
plus, in the man page, -h refers to --help and --flow-control

$ LC_ALL=C agetty --version
agetty from util-linux 2.40-rc2 (flow control, hints, issue, issue.d, keyboard mode, reload, syslog, widechar)

more or less, depending on terminal used, everything prints correctly, except white and lightgray, that print white, and lightgray using previous \e{indication}
