There is no any hints when using "#"

[JasonLeeCn]

Issue Type: Bug

The IntelliSense may stop working when the code (*.c, *.h) using "#".

Eg.:

Have function "test_a", macro "m_EnTestA".

int main()
{
#if m_EnTestA /* No hints when start input 'm' /
#endif
test_a(m_EnTestA); / have hints when start input 't' or 'm' */
return 0;
}

#define ... /* No hints when start input 't' or 'm' */

It doesn't look like auto-complete is supported for # . I tried the following and only got a hint outside the #. Visual Studio does the same.

#define HELLO 1

int main()
{

#if HELLO // no hints for input 'H'
	HELLO // hint when typing here
#endif 

	return 0;
}

Correction, IntelliSense on Visual Studio does support completion for #if via manually invoking completion with Ctrl+Space bar.

On VS Code however, if show completion via Ctrl+Space bar is done it only shows suggestions for the available preprocessor keyboards but not custom defined ones.

inject gramma also has difficulty with whole statement begins with "#"
because it has no name
