#3376 — How to ignore a header line in the stats command?

Goal: automate http://stackoverflow.com/questions/12818797/gnuplot-plotting-several-datasets-with-titles-from-one-file/39211206#39211206 :

Data:

```
a
1, 1
2, 2
3, 3


b
1, 1
2, 4
3, 9
```

Current script:

```
datafile = 'test.dat'
stats datafile nooutput
plot for [IDX=0:STATS_blocks-1] \
    datafile \
    index IDX \
    using 1:2 \
    with lines \
    title columnheader(1)
```

gives a warning:

   "tmp.gnuplot", line 4: warning: bad data on line 1 of file tmp.data

I wish I could write something like:

    stats datafile nooutput columnheader(1)

which would ignore that header

I know about:

    stats datafile name columnheader

but I don't want my `STAT_blocks` variable to change it's name unpredicatably.
