If running with --cygstart, --wait is not respected

[Phidica]

I realised fairly quickly when running this script that unless the --cygstart option was given, if Sublime Text was not already open then the command would block the terminal until ST was closed. I decided to just alias my subl command to always include --cygstart. However I later discovered that if I run subl --wait test.txt (equivalent to subl --cygstart --wait test.txt) then counter to expectation the command did not block the terminal until the file was closed.

I believe this is because the cygstart program is inherently non-blocking, and will not block the terminal even if the ST executable is given the --wait option and is behaving in line with that.

Fortunately, cygstart does support its own --wait option. From my own testing, this issue is fixed if cygstart is given the --wait option when ST is also given the --wait option.
