In particular, we add entries for the two command line options for `make
check` to work, add some whitespace for readability, and enclose the keys
in brackets so `make check` doesn't think the - key is one of the command
line options. We also capitalize Esc and the letter keys for readability.
Based on libexif feature, this patch is adding orientation
detection and provides 2 more shortcuts for live
right/left rotation. Internal version was bumped to 0.7.
