Trim trailing whitespace

Browse Source 
Otherwise `MANPAGER`'s trailing whitespace is escaped, which adds the next line of `export` as part of the command.

```bash
export MANPAGER=env\ BATMAN_IS_BEING_MANPAGER=yes\ bash\ /usr/local/bin/batman\
export MANROFFOPT=-c
```

and you get `cat: export: No such file or directory`
