Eric Blake 1c59bb3cef nice, nohup, su: detect write failure to stderr 
These programs can print non-fatal diagnostics to stderr prior to
exec'ing a subsidiary program.  However, if we thought the situation
warranted a diagnostic, we insist that the diagnostic be printed
without error, rather than blindly exec, as it may be a security risk.

For an example, try 'nice -n -1 nice 2>/dev/full'.  Failure to raise
priority (by lowering niceness) is not fatal, but failure to inform
the user about failure to change priority is dangerous.

* src/nice.c (main): Declare failure if writing advisory message
to stderr fails.
* src/nohup.c (main): Likewise.
* src/su.c (main): Likewise.
* tests/misc/nice: Test this.
* tests/misc/nohup: Likewise.
* NEWS: Document this.

README 

A note about Makefile.am.in.
It is used (usually only by the maintainer) to generate some of the
Makefile.am files in these subdirectories.
