[syslinux] vesamenu.c32: Last line of HELP MSG does not appear

[Sven-Hendrik Haase]

This appears to be a bug:
In case the TEXT HELP for a menu entry extends over several lines and 
you manually set MENU HELPMSGROW and MENU HELPMSGENDROW, the last line 
of the TEXT HELP will not be visible.
Concrete example:
MENU HELPMSGROW 24
MENU HELPMSGENDROW 26

LABEL bug
TEXT HELP
This is the first line, it is visible :D
This is the second line, it is hidden :(
ENDTEXT
MENU LABEL Bug
KERNEL /boot/bug

You can clearly see the TEXT HELP box extending over the right amounts 
of rows, the last line of text is hidden however.
I suppose this is a bug or am I missing something?
