error/0 and error/1 behavior difference

[wader]

jq 1.6 and master does not allow string input or argument

$ jq -n '1 | error'
jq: error (at <unknown>) (not a string): 1
$ jq -n 'error(1)'
jq: error (at <unknown>) (not a string): 1

gojq

$ ./gojq -n '1 | error'
gojq: error: 1
$ ./gojq -n 'error(1)'
gojq: error: 1

I kind of like that it's possible to throw non-string values and catch them. But maybe the difference should be documented?

The exit code is same, and the behavior of gojq looks better. I think fixing it to type error does not change the behavior.

Agreeing, created a PR to document the difference.
