generated doc "Options" for dhcp command drops last line

[Robert P. J. Day]

  just noticed that the sphinx-generated doc page for the "dhcp"
command doesn't display the final line because of this in net/dhcp.c:

BAREBOX_CMD_HELP_START(dhcp)
BAREBOX_CMD_HELP_TEXT("Options:")
BAREBOX_CMD_HELP_OPT ("-H HOSTNAME", "hostname to send to the DHCP server")
BAREBOX_CMD_HELP_OPT ("-v ID\t", "DHCP Vendor ID (code 60) submitted in DHCP requests")
BAREBOX_CMD_HELP_OPT ("-c ID\t", "DHCP Client ID (code 61) submitted in DHCP requests")
BAREBOX_CMD_HELP_OPT ("-u UUID\t", "DHCP Client UUID (code 97) submitted in DHCP requests")
BAREBOX_CMD_HELP_OPT ("-U CLASS", "DHCP User class (code 77) submitted in DHCP requests")
BAREBOX_CMD_HELP_OPT ("-r RETRY", "retry limit (default "__stringify(DHCP_DEFAULT_RETRY)")");
BAREBOX_CMD_HELP_END

  it's that trailing semicolon on the second last line there, which i
suspect shouldn't be there, but if i take it out, the generated line
now literally includes "__stringify(DHCP_DEFAULT_RETRY)”, and i'm not
sure what to do about that, so if someone wants to fix it, go wild.
