Hmm, isn’t it cutting off the last character of text?

Thanks for the patch Tom! I will apply it now.

vis-menu inherited a lot of rough code from slmenu and it really needs
a rework. This certainly fixes one issue.

Hmm, isn’t it cutting off the last character of text?

No, the sizeof operator in C has no knowledge of the contents of the
buffer text. It simply returns the amount of static memory allocated
for it. If sel->text is as long or longer than sizeof(text) then
the string copied into text will not be terminated by NUL (aka \0,
aka 0). text is memset() to \0 at the start of this loop.

Hope this helps!

Thanks Randy. I currently have some time which allows me to look deeper into vis-menu. If I come up with a rewrite or some ideas, I'll let you know.
