Subject: [PATCH] Add shortcut to spawn new terminal in the current dir
This commit is inspired by Santtu's st-newterm-20220221-0.8.5.diff. It
removes the unused res variable, it makes use of _exit() instead of
exit() and it replaces execlp() with execl() (PATH searching is useless
when the path is absolute).
