The dollar sign used to indicate a variable is incorrectly flagged as a prompt in a code block

[giuliazanchi]

A $ sign preceded by " might often indicate a variable rather than a command prompt.

For example:

export PATH="$PATH:/home/user/snap/multipass/common/bin"

Can you provide an example of where this was incorrectly flagged? Current regex ^[ \t]*[$%] should only flag $ when it's the first character in a line with the exception of spaces and tabs.

@SecondSkoll make vale returns two warnings on this page: https://github.com/giuliazanchi/multipass/blob/migrate-docs-to-rtd/docs/how-to-guides/manage-instances/use-instance-command-aliases.md

Hmm, it's not respecting the start of line syntax (^). Strange. Looks like it's some upstream issue.

Try the following syntax, and see what you think:

- '\n([ \t]*|[^\n~]~\]?)(\$|%)'

Run Vale, then change it in your repository, if the Vale config files exist they won't be overwritten again.

The only issue with this solution is that it points at the line above an instance rather than the occurrence itself. It's probably the best we can do for now.
