[O] re-export using same options

[Daniel Clemente]

  Hi, after exporting a subtree to HTML, I do some change and want to export 
again. I find that I have to do a long process to get there:
C-space    C-c C-u   C-c C-e C-s h H    C-u space

  This works, but for every little change I do I have to select again which 
subtree and which format I want.

  Can I re-export using the last settings? If there's a function for that that 
can be invoked with M-x, then only  M-x up RET   will be needed for successive 
reexports.


  Thanks
