Bug 735481 - [PATCH] Mismatch in memory allocation/de-allocation function in vhdlparser/vhdlstring.h

Create an easy possibility to take a snippet from the current file.

Better handling of inline Fortran parameter documentation

Bug 651859 - Brief description misplaced in man page output

Also fixed a parse error when reading a tag file with a Java-style enum

Bug 651850 - @defgroup generates manpage warning

In case the comment for Fortran arguments is empty or just contains @param [direction] <varname> or parts of these. The comment is is not shown and (depending on the configuration settings, a warning is given).
Also the detection of inconsistencies between intent attribute and documentation has been improved.

In case the \cite command is used but no entry for it is given in a bib file no warning is given as the CiteInfo entry is present with the right label, but the text item is empty and this is not tested.

(also corrected an error message on opening a file)
