Be aware that in general, replacing - with '' or : is wrong: POSIX
requires "trap '' 0" to ignore the signal, and "trap : 0" to execute the
(no-op) : on occurance of the signal, rather than restoring the default
behavior.  But in the special case of signal 0, doing nothing at exit
happens to be the default behavior, so if this works, we might as well
document it and fix install-sh accordingly.
