#111 --tab causes buffer overflow

[Anonymous]

If I use --tab without argument, global_options_workspace is set to WORKSPACE_UNDEFINED.

This causes a buffer overflow at line main.c:83 (roxterm-2.9.7):
sprintf(tmp, "--tab=%u", global_options_workspace);

tmp is defined as char[16].

The buffer should be larger, and snprintf should be used.

Thanks. I've fixed that in git and replaced one or two other sprintfs where I couldn't be confident about the upper limit.
