[PATCH] Use user.name and user.email in import-tars.perl

Mimic what is done in git-import.sh and git-import.perl

 And that made me wonder if it wouldn't be worth, actually, to have
 git config user.name and git config user.email return the "magic" values
 gotten from guessing in ident.c when no value is in the config. That would
 allow scripts, which have no other simple means to get the user name and
 email, to have the same feature as builtins.
