Show progress/pulse while converting or indication of "not found"

[aakropotkin]

Some kind of indication that your requested info pages are "being processed, please wait", or a progress bar would be nice.

Even running the suggested :Vinfo libc took ~30 seconds to process on my box, and I only realized that the plugin worked after the 3rd try when I was literally editing my plugin list in another buffer to remove it.

Adding a "could not find infopages for X" goes hand in hand with this. Since generating pages takes a while, if I misspell a page I have no idea until I watch the pot for ~1 minute and resign myself to "guess it doesn't exist?"
