Source path glob patterns do not work for a single match

[AlekSi]

Documentation recommends to use source_path: cmd/* for idiomatic Go projects. However, this explodes if there is only one match (and possibly zero; did not test this case).

🚀 thanks for the bug report. The root cause is a (potentially wrong) check on whether expanding a source path did result in an expansion. I'll take a look at handling this better 👍
