Redundant suggestion printed on an UndefVarError on nightly

[jishnub]

julia> a
ERROR: UndefVarError: `a` not defined in `Main`
Suggestion: check for spelling errors or missing imports. No global of this name exists in this module.

The suggestion text "No global of this name exists in this module" appears to repeat the error message "a not defined in Main", and in less-obvious language. It's also not a suggestion, but an observation.

Formally speaking, the message is telling you that there is also no global a declaration anywhere, as opposed to the first text that is just telling you !isdefined(Main, :a), so it is the error message that is the repeat of the observation, not the reverse.

There is both a suggestion followed by an observation, separated into sentences by a period.

This distinction seems quite technical, and wasn't obvious to me despite being relatively familiar with Julia. I wonder if the framing might be improved? Also, perhaps the observation should precede the suggestion to avoid it being seen as a part of the solution. As a non-native speaker, "No global of this name exists in the module. Suggestion: check for spelling errors or missing imports" sounds clearer.
