Hello,

gtkdoc-scan fails when struct definitions are indented with whitespace:
----------------------------------------------------------------------
(sid)ametzler@argenau:/tmp$ rm -f foo-decl-list.txt ; echo testin/foo.h: ; cat testin/foo.h ;  gtkdoc-scan --module=foo --source-dir=testin  ; echo foo-decl-list.txt: ; cat foo-decl-list.txt
testin/foo.h:
#define NUMBERX 42

  struct foo_st
  {
    const char *name;           /* Name */
  };
  typedef struct foo_st foo;

#define NUMBERY 23
foo-decl-list.txt:
<SECTION>
<FILE>foo</FILE>
NUMBERX
</SECTION>

(sid)ametzler@argenau:/tmp$ rm -f foo-decl-list.txt ; echo testin/foo.h: ; cat testin/foo.h ;  gtkdoc-scan --module=foo --source-dir=testin  ; echo foo-decl-list.txt: ; cat foo-decl-list.txt
testin/foo.h:
#define NUMBERX 42

struct foo_st
{
  const char *name;             /* Name */
};
typedef struct foo_st foo;

#define NUMBERY 23
foo-decl-list.txt:
<SECTION>
<FILE>foo</FILE>
NUMBERX
foo_st
foo
NUMBERY
</SECTION>
----------------------------------------------------------------------

This applies to both 1.25 and 1.26.
