[PATCH] get_maintainer: Emit longer section headers

[Joe Perches]

Section headers can be quite long and some are very long
and duplicated for many initial characters.

The current maximum length emitted for a section header
is 20 bytes (or 17 bytes then ... when the section header
length is > 20).

Change that length to 50 so more of the section is shown.

Example new output:
$ ./scripts/get_maintainer.pl -f drivers/net/ethernet/broadcom/bnx2x/
Ariel Elior <ariel.elior@xxxxxxxxxx> (supporter:BROADCOM BNX2X 10 GIGABIT ETHERNET DRIVER)
netdev@xxxxxxxxxxxxxxx (open list:BROADCOM BNX2X 10 GIGABIT ETHERNET DRIVER)
linux-kernel@xxxxxxxxxxxxxxx (open list)

Old:
$ ./scripts/get_maintainer.pl -f drivers/net/ethernet/broadcom/bnx2x/
Ariel Elior <ariel.elior@xxxxxxxxxx> (supporter:BROADCOM BNX2X 10...)
netdev@xxxxxxxxxxxxxxx (open list:BROADCOM BNX2X 10...)
linux-kernel@xxxxxxxxxxxxxxx (open list)
