Auto Complete won't work when typing in single line $$

[WuYuanhun]

Trying to use latex auto complete, it works when typing as plain text.
It works in multi-line $$.
But when I try to type between in single line $$, the auto complete just does not pop out.

For example, auto complete works in:

$$
\A
$$

but does not work in :

$\A  $

Update the trigger conditions.
The auto complete only works when the character beside '' is in [ ' ', '\n', '\r'].

Start to wonder if this is a feature other than bug...

You’re right, there needs to be a whitespace character to the right otherwise autocomplete won’t trigger, this is by design. But this should not occur inside inline maths, since it’s very common to be typing LaTeX commands inside $$ without whitespace.

I pull a merge #58 to fix it.
And test on my Mac successfully , (which may have little possibility to cause any problem because only changed a line of code)
Feel free to leave feedback
Thanks for review and Pine!
