When system calls indicate an error they return -1, not some arbitrary

value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

No need to declare variable name as static in dounsetenv(). Also, drop a

the input buffer instructs csh that the buffer contains a complete command.

Postpone printing of prompt if filec is enabled in csh. Any I/O should be
