`ignore_status` should take a boolean argument

[Alex Kladov]

We should spell it as .ignore_status(true), to match .echo_cmd() and in general to be a friendlier API. Sadly, that would be a breaking change.

We do have set_ignore_status:

xshell/src/lib.rs

Lines 877 to 880 in 11ab785

 /// Controls whether non-zero exit status is considered an error. 
 pub fn set_ignore_status(&mut self, yes: bool) { 
     self.data.ignore_status = yes; 
 }
