I think this type of test is overused; I see it in other scripts also. The
single line 'source /etc/profile' works just fine: if /etc/profile exists and
is readable, 'source /etc/profile' does just what you expect. If, for some
reason, the file doesn't exist or is not readable, 'source /etc/profile' will
produce an error message, which again is probably what you want. Basically
the 'source' instruction already does the test for you, so you don't need to
double the work.
