We use package 'tasklog' to print progress messages to the command line
interface, as in the case of 'git-migrate-import(1)' or
'git-lfs-prune(1)'.
This package aims to mimic the style of upstream Git's progress log
lines, which are identical in every way, except for the trailing period
at the end of 'done'.
Git does print this period, but Git LFS does not. Let's make the two
more similar by having LFS print this period, too.
