 Replying to [comment:1 hamish]:

 requiring to use an extra flag?

 level 1 for v.info.

 Right. v.info no longer needs level 2, it tries level 2 first, if this is
 not successful, it tries level 1.

 There is also no need to force level 1 just to speed up things, because
 v.info opens vectors with head only when trying level 2. At least this is
 the original behaviour in 6.4 and earlier, it was changed recently for 6.5
 and 7, I changed it back to head only. There is no need to fully open a
 vector if level 2 is available.

 In short, whatever happens, v.info is lightening fast and uses nearly no
 memory. The level 1 option can go.

 Um, v.info is fast on cli but slow when used within wxGUI with a large
 vector, but that's a wxGUI thing, wxGUI collects some vector information
 first before it allows you to run a module.
