Reverting to previous; apparently this was a bug in doxygen 1.7.4's support
of header markdown.
The following is valid, documented, "standard markdown" for headers in
doxygen:

    This is a level 1 header
    ========================

    This is a level 2 header
    ------------------------

Upgrading doxygen from 1.7.4 to 1.8.13 fixed the problem.
So beware of 1.7.4 wrt to these kinds of header markdown;
the result in the docs was no header, the header text + underbars
were appearing inline with the text, crlfs removed.

Not sure exactly what version of doxygen this was fixed in;
a search in their bugzilla for 'headers' seemed to show no
directly relevant matches, other than maybe bug #681898.

Doxygen fix: The trick of using a line of dashes under a section heading no
longer works.

This has been working fine for years, not sure what version of doxygen
dropped this.
I'm running 1.7.4 here, and that trick isn't working for the Fl_Browser_.H
docs.

Changed to using <B> and </B> and <BR> which seems to work OK in both HTML
and PDF
generation.

Fixed small doxygen inconsistencies for do_callback value.

Internally Fl_Browser passes the raw value of when() as the
"do_callbacks" value, so it's important that ALL non-zero values
mean "do the callback' (and not just 1).

SVG support: draw images at full screen resolution also when there are
several pixels per graphical unit, as with Apple retina displays.

Fluid: remove redundant code, fix FL_IMAGE_LABEL labeltype.

Remove leading underscore from _FL_IMAGE_LABEL.
Remove redundant assignment of image().

Thanks to Greg for finding these issues.

Remove leading underscore from labeltyps as far as possible.

Removed obsolete '\todo' item from docs (done with recent commits).

Removed redundant code from label assignment (e.g. use FL_IMAGE_LABEL
instead of label type assignment + use of _FL_IMAGE_LABEL).

See recent commits.

Remove leading underscore from labeltype(s) in new demo.

Since svn r12443 we can use all labeltypes (including FL_IMAGE_LABEL and
FL_MULTI_LABEL) w/o leading underscore. We can also use both documented
variants to assign an FL_MULTI_LABEL to an Fl_Menu_Item.

Add missing Fl_Labeltype and Fl_Boxtype definitions.

Some labeltypes and boxtypes were missing a #define for the enum
without a leading underscore and the corresponding setup function
to initialize the internal table of boxtypes and labeltypes, for
instance _FL_MULTI_LABEL. This is now fixed so (hopefully) all boxtypes
and labeltypes can and _should_ be used w/o leading underscore.

Note: if there are still boxtypes or labeltypes that can't be used w/o
leading underscore this should be considered a bug and is to be fixed ASAP.

Fix compiler warning and potential error in PNG error handling.

Compilation with gcc -Wall -Wextra displayed the following warning:

Fl_PNG_Image.cxx: In member function 'void Fl_PNG_Image::load_png_(const
char*, const unsigned char*, int)':
Fl_PNG_Image.cxx:118:9: warning: variable 'fp' might be clobbered by
'longjmp' or 'vfork' [-Wclobbered]

Making the variable static and initializing it properly avoids this
potential error in the PNG lib's error handling.
