The repository's file is queried if $user is
already present before attempting to add him/her.
A bug that made cvsdadm crash with the "disable"
function was fixed. The program now prints whether
a user is enabled or disabled in Query mode. The
program exits with status 0 instead of 1 in
interactive mode. Some other minor bugs were
fixed.
If -R is not given, the tool will now try to check that the repository is in the current working directory. &Init_repository now verifies if the repository is in a sane state before attempting any operation. A new -C command creates a repository when given a -R argument and nothing else, or creates the repository files if any other flags are given. Better handling and logic was provided with interactive mode. Some redundant lines of code were removed.
