* docs/grub-dev.texi (Font Metrics): Exclude @image command from DVI
builds, since we don't have an EPS version of font_char_metrics.png.
Add leading dot to image extension per the Texinfo documentation.
Add a new timeout_style environment variable and a corresponding
GRUB_TIMEOUT_STYLE configuration key for grub-mkconfig. This
controls hidden-timeout handling more simply than the previous
arrangements, and pressing any hotkeys associated with menu entries
during the hidden timeout will now boot the corresponding menu entry
immediately.
GRUB_HIDDEN_TIMEOUT=<non-empty> + GRUB_TIMEOUT=<non-zero> now
generates a warning, and if it shows the menu it will do so as if
the second timeout were not present. Other combinations are
translated into reasonable equivalents.
Remove reference to grub-default from description of saved default entry.
Also mention that GRUB_DEFAULT=saved depends on availability of environment
block.
