Assigning to Joerg as he is familiar with the patch-headers.py script.

First investigation makes me think this is related to the
script that builds vectortable.dox.

It's a documentation-only bug, i. e. the vector names itself
are consistent with the way they have always been in avr-libc
for these devices. Old-style SIG_XXX vector naming is
deprecated anyway.

Found discrepancy between documentation (online, currently ver 1.6.1)and iomxx4.h (CVS: 1.13.2.3; 1.17) - differences marked with '*'

doc/avr-libc/avr-libc-user-manual/group__avr__interrupts.html defines

USART0_RX_vect SIG_*UART0*_RECV USART0, Rx Complete
USART0_TX_vect SIG_*UART0*_TRANS USART0, Tx Complete
USART0_UDRE_vect SIG_*UART0*_DATA USART0 Data Register Empty

While iom44x.h defines:

/* USART0, Rx Complete */
#define USART0_RX_vect _VECTOR(20)
#define SIG_*USART*_RECV _VECTOR(20)

/* USART0 Data register Empty */
#define USART0_UDRE_vect _VECTOR(21)
#define SIG_*USART*_DATA _VECTOR(21)

/* USART0, Tx Complete */
#define USART0_TX_vect _VECTOR(22)
#define SIG_*USART*_TRANS _VECTOR(22)
