[Monotone-devel] [PATCH] improve db error handling

[Neil Conway]

This trivial patch improves the error handling performed by a few of the
"database" subcommands. Namely:

% file nonexistent
nonexistent: ERROR: cannot open `nonexistent' (No such file or
directory)
% monotone --db=nonexistent db version
database schema version: da39a3ee5e6b4b0d3255bfef95601890afd80709
% file nonexistent 
nonexistent: empty
% rm nonexistent

% monotone --db=nonexistent db migrate             
monotone: error: database schema
da39a3ee5e6b4b0d3255bfef95601890afd80709 is unknown; cannot perform
migration
% file nonexistent
nonexistent: empty

Those subcommands now both error out sanely if the database does not
exist.
