Syntax highlighting for string formatting misses "% 8.2e"

[pwintz]

Describe the bug
The syntax highlighting for string formatting specifications, as used in fprintf, do not accurately highlight format specifications for %e that uses a space before the e, like % 8.2e.

In this image, note that %+8.2e is correctly highlighted where as % 8.2e is not.

Thank you for reporting this!

This is not directly related to the MATLAB extension for VS Code, but rather the grammar we leverage for syntax highlighting. I am going to move this issue over into the MATLAB Language grammar repository.
