PATCH: context in completion widgets

PATCH: context in completion widgets

[Sven Wischnowsky]

Playing with `_expand' some more showed a bug in the completion code:
it didn't copy the value of `inwhat'. The parameter expansion magic in 
`_expand' made this be set and later tests in tricky.c ended up
thinking they were in a math environment.

Bye
 Sven
