Comment(by jreed):

 I tested loadzone from branches/tingting-loadzone at revision 1901.

 The "including" line is printed even if not interactive.

 Also carriage returns are printed. Maybe that is not needed when printing
 the "included" line.

 If included zone filename is too long, it is cropped. So may be hard to
 read with long path. Maybe crop in middle and add ... dots? or just show
 basename of filename?

 Maybe add a space after "seconds(s)" or before "(.*%" percentage)

 Also for verbose, it may be useful to know if this data is overwriting or
 replacing existing zone or existing records.

 I am unclear what the % percentage means. Sometimes I finishes with 0%,
 100% or 99%. I didn't look at code to figure this out.

 Maybe add a space after colon in error messages (so doesn't have text
 immediately after colon).

 Overall looks great!
