'+' or ' ' flag in Printf (et al) doesn't seem to work for positive or zero values #278
Description
by mkoistinen:
Before filing a bug, please check whether it has been fixed since
the latest release: run "hg pull -u" and retry what you did to
reproduce the problem. Thanks.
What steps will reproduce the problem?
1. Run this code:
--- snip snip ---
package main
import . "fmt"
func main() {
Printf("Test of Printf() string '+.3e': [%+.3e] [%+.3e] [%+.3e]\n", 0.0,
-1.5, 10000.5);
}
--- snip snip ---
Output should be:
Test of Printf() string '+.3e': [0.000e+00] [-1.500e+00] [1.000e+04]
2. Notice the lack of the '+' sign in front of the returned 1st and 3rd values
3. Compare to specification in `man printf` on your system
What is the expected output? What do you see instead?
The output SHOULD be:
... [+0.000e+00] [-1.500e+00] [+1.000e+04]
Also, same for the ' ' flag, which should put a space before positive
numbers instead of the '+' symbol above.
What is your $GOOS? $GOARCH?
GOARCH=amd64
GOOS=darwin

Sorry if this has already been fixed since this version, but I am working
on code for another system, and must maintain the same version locally as
the remote system.
