Description:
------------
Format specifier %e (scientific number) in sprintf() function gives results with wrong number of decimal digits and in one particular case it gives a mess.

Reproduce code:
---------------
echo sprintf("%e\n", 1.123456789);
echo sprintf("%.10e\n", 1.123456789);
echo sprintf("%.0e\n", 1.123456789);   // this gives a mess
echo sprintf("%.1e\n", 1.123456789);
echo sprintf("%5.1e\n", 1.123456789);

Expected result:
----------------
1.123457e+0
1.1234567890e+0
1e+0
1.1e+0
1.1e+0

Actual result:
--------------
1.12346e+0
1.123456789e+0
.0e+0123456789     
1.e+0
1.e+0
