Fix syntax highlighting synchronization

[amiralies]

Closes #14

[amiralies]

according to vim docs (:h :syn-sync-first),
syntax sync fromstart is equivalent to using a large value for minlines.
This is what vim-javascript uses.
I think this solves sync issue for all cases, maybe wen can go with this for now and if we faces performance issues we can use an optiomal value for min / max value

I tend to have enormous ReScript files (just check the re_pages/Playground.res file, that spans more than 1500 lines), I'd rather would like to try a line number of 600 or so

I think JavaScript workflows are different, because they tend to create a hundred 10 line files, instead of one 1000 line file

[amiralies]

You're right, long js files are headache but it's so natural to have large files in a language with ml style typesystem like ReScript.
IMO I don't think if it causes major performance issues but yeah we like vim because it's FAST. so for now we go with 600 and if we had problems (either large multiline strings or large comments) with this we can tweak the number or use sync fromstart.

[ryyppy]

Yeah let's keep an eye on that. I think 600 will be fine, just don't want to stress vim too much early on

thanks!
