suspend SIGTSTP

[FxIII]

suspending a running ptpython somehow messed up the newline for the terminal: when shell input reaches the end of the line the subsequent output si written in the same line.
if I recover ptpython and exit the terminal works as expected.
probably there is some sort of cleanup and recover need to be done in SIGSTP/SIGCONT.

Hi @FxIII,

Thanks for pointing out! This is a bug indeed. I'll try to fix it - shouldn't be too hard.
