Hullo, can someone tell me what's the difference between \skip and \unskip and when to use them?
I've already checked the wiki and the references, but cannot find a definition
of either.
Here's a use case that's giving me headaches for quite some time:
In my bibliography I often have items that are missing one or two fields (e.g.
legal texts with or without amendments etc.) and I have to tell ConTeXt to
skip those. From trial and error I learnt that:
* \skip leaves me with the punctuation and styling around the skipped
field (e.g. a trailing ", ." or "( )")
* \unskip seems to do what I want, but generates the following error
every
time 'context' reaches an '\unskip' entry:

A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)
