Partial support for g:gutentags_ctags_extra_args

Hello,

Autosar uses for C development certain compiler abstraction macros like:

#define FUNC(rettype, memclass)

One way to generate a correct tags file is to call ctags with -D "FUNC(rettype, memclass) memclass rettype"

When I try to use let g:gutentags_ctags_extra_args += '-D FUNC' everything is working as expected.

More complex macro definitions need to be surrounded by quotes like in the case of -D "FUNC(rettype, memclass) memclass rettype".

In ctags.vim:137 when calling shellescape the double quotes are escaped ending with -D ""FUNC(rettype, memclass) memclass rettype"" which cannot be interpreted by ctags.

The name of the parser: universal-ctags

The content of input file:

#include <stdio.h>

#define FUNC(rettype) rettype

FUNC(int) fnct(int a);
FUNC(int) fnct(int a)
{
  return a;
}

int main(void)
{
  int a = 1;
  printf("%d\n", fnct(a));
}

The tags output you are not satisfied with(ctags main.c):
