[Libguestfs] [PATCH libguestfs 4/5] guestfish: diagnose stdout write failure

[Jim Meyering]

From: Jim Meyering <meyering at redhat.com>

Use gnulib's closeout module to ensure any failure to write to
stdout is detected and reported.
* fish/fish.c: Include "closeout.h".
(main): Call atexit (close_stdout);
* bootstrap (modules): Add closeout.

(emit print_*_indent): Likewise, s/int/unsigned int/
