[Pasdoc-main] Full support for "deprecated 'followed by a string'"

[Michalis K. <mic...@gm...>]

Hi,

I just committed a small improvement to PasDoc:full parsing and showing of

  deprecated 'followed by a string'

declarations. This is useful to document *why* some identifier is
deprecated, it's understood both by compilers (FPC, Delphi since 2010)
and now by PasDoc too :)

Previously, there was a code to skip it (but only in certain
situations, for procedures/functions --- but not e.g. for classes).
Now it is actually understood by PasDoc (read to
TPasItem.DeprecatedNote), for all cases, and shown in the output
documentation (HTML and LaTeX). It even works for tricky cases like

  procedure MyProc3; deprecated #72#$6 'llo'; // this says 'Hello'

Tests are welcome of course :) My testcase is in SVN in
tests/ok_deprecated_directive_note.pas, see
http://svn.code.sf.net/p/pasdoc/code/trunk/tests/ok_deprecated_directive_note.pas
.

Regards and happy coding in the new year! :)
