[parted-devel] [PATCH 05/10] Ensure "blank" cmd-line before ped_exception_throw

[Joel Granados Moreno]

When ped_exception_throw requires input from the user and there are
leftover strings in the command line, there is an "invalid token" error
from parted.  This happens because the ped_exception expects some input
that is, most likely, different from the leftover string(s).  To address
this, one must make sure that all the argument strings are parsed before
invoking any exception that requires input.

* parted/parted.c (do_mklabel): Put the command_line_get_disk_type call
before the disk checks (_disk_warn_loss will call ped_exception_throw)
* tests/t0000-basic.sh : The output needs not to include the error
message.
