USE_LED ... LED not lit when USE_ENTER_DELAY = no and USE_ENTER_PIN = yes

[sloped-soarer]

Entry
USE_ENTER_DELAY = no
USE_ENTER_PIN = yes
USE_ENTER_UART = no
USE_ENTER_I2C = no
USE_ENTER_FIFO = no

Communication
USE_LED = yes
USE_UART = yes

What appears to be happening is that the LED is lit during initialisation and then turned off when the bootloader in entered by the toggle code.
The line val = get_char(); appears to be blocking and so the LED remains off until the bootloader processes some serial input.

Suggest moving the LED toggling code below val = get_char(); so that a positive visual indication is given that the bootloader has been entered.

e.g.

// Main bootloader
while (in_bootloader) {
val = get_char();

#ifdef USE_LED
#ifdef AVR_XMEGA
LED_PORT.OUTTGL = (1 << LED_PIN);
#else // AVR_XMEGA
LED_PORT ^= (1 << LED_PIN);
#endif // AVR_XMEGA
#endif // USE_LED

....

Thanks for the work so far on this project.
