Snapshot of SVN 3109

• New tl-analysis module for decomposing and analysing token lists on a token-by-token basis.
• Extend l3regex to work with tokens where appropriate. In particular, the syntax c{<csname>} can be used to match control sequences.
• Improved robustness of regex system.
• Improve behaviour of DeclareExpandableDocumentCommand such that optional arguments (o, O, d and D) can contain nested delimiter tokens in the same way as happens for non-expandable functions.
• No longer accept l type arguments for DeclareExpandableDocumentCommand, as this was not reliable.
• Added expandable l_if_empty:x(TF) test.
• Add experimental 'list comprehension' functions seq_(g)set_filter:NNn and seq_(g)set_map:NNn.
• Improve the behaviour of vbox_... and vtop... functions so that they always end with a par rather than the internal TeX /end_graf/ procedure.
• Revise cs_to_str:N such that it requires exactly two expansions and is faster.
• Revise register allocation such that a full set of registers are accessible using the native allocator when using LuaTeX.
• Revise cs_show:c and cs_meaning:c to test explicitly for undefined arguments.
• Revise some internals of ior/iow stream allocations.
• Make l_replace_... functions robust inside halign.
• Fix bugs in the l_rescan... functions to handle & correctly and to preserve braces under all circumstances.
• Fix bugs in LuaTeX-only catcode table allocator (IniTeX mode only).
• Test that catcode tables are new when allocating in package mode.
• Tighten up on use of _nopar so that it is only applied to functions with no arguments.
• Documentation fixes for prg_(new|set)_eq_conditional:NNn.

thanks for the uploads; i've installed the new versions, and updated the three entries in the catalogue repository.

The catalogue entries will change (somewhat) overnight tonight.
