As with "file_write_error_message()", so with

"file_close_error_message()" - but just use "file_write_error_message()"
for UNIX-style errors, under the assumption that a close will only fail
because a buffer-flushing write fails or because "close()" itself fails
when, for example, pushing unsynced NFS client-side writes out over the
wire.

Make several routines in "print.c" return success/failure indications.

Check for write errors when printing "Follow TCP Stream" stuff or saving
it to a file.
