Fix for missing space after \endlink in doxygen

The "endlink" command is processed in processWordCommands, which by
default skips space occuring after the command, which is intended for
removing leading space from a command argument.  For "end" commands,
we don't want to do this.  Note that certain end commands such as
"endcode" aren't processed by processWordCommands (believe
addCommandUnique ends up handling them).

Update usage of \link in doxygen_translate_all_tags.i to test handling
of space after \endlink.

Tweaking some of the usage in doxygen_misc_constructs.i to remove what
seems to be an extra space from the input (otherwise we would need to
add an extra space to the expected output).
