Recognizing subroutine definitions.
Recognizing subroutine definitions.

To prevent the recognition of e.g. `sub` in:
```
my %SenderArgs = (
  sendmail  => [],
  smtp      => [],
  sub       => [],
);
```
as start of a subroutine (and giving in doxygen the warning:
```
warning: member with no name found.
```
the recognition of subroutines has been adjusted.
