Improve format of Gina-log buffer

[obcat]

I changed the format of Gina-log buffer. How about this?

Changes

• Truncate commit summary (length: 30). Using this placeholder:

  %<(<N>[,trunc|ltrunc|mtrunc])
  make the next placeholder take at least N columns, padding spaces on the right if necessary. Optionally truncate at the 
  beginning (ltrunc), the middle (mtrunc) or the end (trunc) if the output is longer than N columns. Note that truncating only 
  works correctly with N >= 2.

• Use the "human" date format.

  --date=human shows the timezone if the timezone does not match the current time-zone, and doesn’t print the whole date 
  if that matches (ie skip printing year for dates that are "this year", but also skip the whole date itself if it’s in the last few 
  days and we can just say what weekday it was). For older dates the hour and minute is also omitted.

• Remove brackets around author name.

  <author> -> author

If you don't like anything, please feel free to point out. (Especially the last one is just my preference...)

I've lost motivation for this... so closing.

Thanks.
