Confusing warning message for location blocks.

[snigel]

When location regexes such as ~^ doesn't contain a space ie:

location ~*^/if-and-alias/

nginx accepts the configuration but the linter will show an incorrect error message:
"error Expected string when using 'location', got regular expression"

This message disappears as soon as the location is using a space.

location ~* ^/if-and-alias/

It would be nice if the linter suggested to add the space instead.
