If the work tree's path prefix does not exist in the first of the two trees, then 'got cherrypick' failed with "no such entry found in tree". But this is a legitimate situation, as shown in the new test added here. The first tree could be the empty tree, for example, which should result in 'got cherrypick' adding all files from the second tree instead of complaining about a non-existent path-prefix directory in the first tree.

Remove the alias 'got in' for 'got init'. The 'in' alias was too close to either 'init' or 'info'. ok tracey, millert

with input from + ok tracy and millert
