Fixed the block comment scope for the Matlab syntax

Originaly pointed out on:

1. https://forum.sublimetext.com/t/matlab-syntax-highlighting-error-on-mac-10-11-4-build-3114/23429/2

Tests results after this work:

1.

The regex should be (%\{)\s*\n, so that the punctuation scope is applied to the %{.

[wbond]

Though not changed by you, the match on line 72 should have () around the %\} also.

[evandrocoan]

Updated.

[wbond]

We should probably also add support for these block comments to https://github.com/sublimehq/Packages/blob/master/Matlab/Miscellaneous.tmPreferences#L35-L40.

[evandrocoan]

Added.

[wbond]

Thanks for these fixes!

[evandrocoan]

you are welcome. However there is bug I forgot to go after before. Here:

<string>%{\n</string>
...
<string>%}\n</string>

It is obligatory a new line to be inserted, otherwise the the block comment does not work. How could a new line to be inserted?

There is also a missing new line on the opening and the closing does also need new lines:

<string>\n%{\n</string>
...
<string>\n%{\n</string>

I am gonna try:

<string>
%{
</string>
...
<string>
%}
</string>

Take care also when inserting the new files for \n%{\n, to keep %{ correctly indented.

The Syntax

The syntax also need to be fixed to not allow anything than spaces/tabs, before and after the symbols %{ and %}.
