[Qemu-devel] [PATCH v2 3/5] qemu-img: avoid excessive BlockFragInfo line length

[Stefan Hajnoczi]

The qemu-img check printf() statement that shows BlockFragInfo results
is poorly formatted.  Introduce a local variable to shorten the lines
and restore proper indentation.

The next patch adds a field to BlockFragInfo so it is beneficial to
straighten out this code before modifying it.
