[Rd] chron library: format.times, parse.format and h:m (PR#8507)

[spector@stat.Berkeley.EDU]

Due to the following lines in parse.format:


else if (nf == 3) {
        sep <- ""
        fmt <- substring(format, first = 1:3, last = 1:3)
    }

If a format code has 3 characters, it will not use a separator:

> library(chron)
> mytime = times('7:15:00')
> format(mytime,'h:m')
[1] "0715"
