read_from use makes normal use of a calendar id not working

[keul]

A configuration like this one should be possible?

id	name	read_from
xxxxx1	Cal1	xxxxxx2
xxxxx2	Cal1

Line 1 is the canonical way of using the read_from feature, but what is the use want to define an event directly on Cal1 using xxxxx2? This makes the feature going crazy.

• should be possible? or…
• should be reported as an error?

I need this! Probably the best/simpler way is to support just this in one line:

id	name	read_from
xxxxx1	Cal1	xxxxxx2

So both xxxxx1 and xxxxx2 should be alias of Cal1
