shift-alt-F adds blank lines at the end of file every time it's called

[Denis Davydov]

I have a custom astylerc file which works flawlessly with astyle@2.04 from the command line.

However, when I use the plugin and provide

"astyle.executable": "<blabla>",
"astyle.astylerc": "<blabla>",
"C_Cpp.formatting" : "Disabled"

I see interesting behaviour that each invocation of formatting adds a new line:

p.s. macOS 10.13.3, astyle@0.7.1, VSC@1.12.0.

@welkineins any idea what can be wrong?

I have this problem, too. However, this problem only appears in astyle@2.04. There does not have this problem in astyle@3.1.

Refer to the differences between the two versions. This is my patch for astyle@2.04 to fix this bug:
