[NTG-context] gobbling previous space

Dear gang, For some macro writing, I need a low-level command that will gobble the space before it so that ========= Here is some text.% \mycommand ========= is equivalent to ========= Here is some text. \mycommand ========= without the %. I'm sure there's a context command for this hidden somewhere...
