* utils.c (error): if error_pre_print is set, print the string

first.
* main.c (main, print_gnu_advertisement, print_gdb_version):
Reformat legalese so it always prints, but acts as an "I'm here"
message while symbols are being read.  If any errors occur,
print a few newlines to set off the message and start it at the
left margin.  Remove mention of "help" command, and don't yak about
symbol reading.
(catch_errors):  Error string is now printed first in case of
error, not last.
* command.c (undef_cmd_error, lookup_cmd):  On undefined command,
suggest the "help" command.

* Makefile.in (VERSION):  Set to 4.0.2.
