Allow merging a single file

[charlax]

Should yq allow merging a single file? I know it does not make any sense to merge a single file, but it does make scripting with yq a lot simpler if it accepts a single file as the merge command input.

% yq m --allow-empty .custom.yml | yq r - -j
10:40:44 main [ERRO] Must provide at least 2 yaml files
panic: attempted to parse unknown event: none [recovered]
	panic: attempted to parse unknown event: none

Otherwise, yq could include a --allow-single flag to accept this behavior.

Thoughts?

No strong opinion... anyone else looking for this feature?
