Command \ilinebr reamained

When having the alias:
```
ALIASES += sbl_add_package_main_class{4}="\addtogroup \1-ref-manual ^^ @{ ^^ \class \2 ^^ \brief \3  \4 ^^ @}"
```
for the comment block:
```
/**
     \sbl_add_package_main_class{Molecular_potential_energy, T_Phi_psi_dihedral_angles_visitor,
      Defines iterator over all successive pairs of dihedrals.,
     \details Defines iterator over all successive pairs of dihedrals.
     \tparam CovalentStructure The type of the input covalent structure
     }
  */
```
we get the warning:
```
warning: the name '\ilinebr' supplied as the argument of the \class, \struct, \union, or \include command is not an input file
```

The problem was that the rule:
```
<ClassDocArg2>{FILE}|"<>"               { // second argument; include file
```
took the `\ilinebr`, the rule:
```
<ClassDocArg2>{DOCNL}                   {
```
should habe been checked before.
