Handle += of both strings and lists. If += is used for config options expected to be numbers, then a warning is printed and the config option ignored (because xl ignores config options with errors). This is to be used for development purposes, where modifying config option can be done on the `xl create' command line. One could have a cmdline= in the cfg file, and specify cmdline+= on the `xl create` command line without the need to write the whole cmdline in `xl' command line but simply append to the one in the cfg file. Or add an extra vif or disk by simply having "vif += [ '', ];" in the `xl' cmdline. Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>
