#13 variable names with underscore invalid in .pyxplotrc

[Anonymous]

although assignments such as
> a_b = 3
are legal in the manual (and work on the command line), writing them in configuration file (section [variables]) leads to
Error in line 10 of configuration file .pyxplotrc: Illegal variable name

Thanks for your bug report. This has been fixed in Pyxplot 0.9.0.
