BTW, to make code clean, I would further change my cygwin checking to using the `go#util#IsCygwin` created in this [PR](https://github.com/fatih/vim-go/pull/3611#pullrequestreview-1795474217) after it's merged.

@bhcleek Totally agree. Thanks for your kind reply and detailed explanation. Thanks for keeping an eye on my changes, that's very kind of you, and your direction is totally correct....

welcome, happy holiday !

@bhcleek Thank you for your guide and instruction. I added cygwin detection `go#util#IsCygwin`. The reason using `uname` to check the platform is inspired by the [maven-wrapper](https://github.com/takari/maven-wrapper/blob/2b2c15adc38acfcf17533f5d7aff220ba87256ba/mvnw#L49) project, which is widely...

By the way, I found there is a util function `go#util#IsUsingCygwinShell` which might not correct, because it uses `go#util#IsWin`, but based on my above testing result, `go#util#IsWin` always return 0...

As CYGWIN uses `cygstart` instead of `start`, but MSYS2 and GitBash uses `start`, I made the cygwin checking as a seprated "elseif", and use `rundll32` instead of `start rundll32` or...

I'm on windows, use the following keymap as highlighting words is not a frequent action as copy/paste does : { "keys": ["ctrl+super+j"], "command": "text_marker" }, { "keys": ["ctrl+super+h"], "command": "text_marker_clear"...

Now, by configuring text marker setting file, user can define at least 10+ colors and mark accordingly in order. pls check updated readme.
