Making the prefix visible is a good idea.  I think that it is more compelling if every line is prefixed.  It creates a good contrast between recipe lines and multi-line variable definitions.

Having to leave off a prefix or two is not to bad.

I didn't notice that blank lines were allowed in recipes.  (i.e. I never read to the end of the paragraph.)  Blank lines introduce deceptive visual breaks, where a visible prefix provides continuity.

Thanks for the consideration.

I agree that this is not right.  The handling of the prefix character needs a bit of work.

However, I should say that I intended the prefix character to ONLY be used to introduce the initial line of a recipe.  Maybe that intention needs some rethought.

I'll leave this open to consider it.

I now realize that the TAB, could be inserted, and then removed by filter-out.

The default .RECIPEPREFIX (TAB) allows line continuation inside function calls.

Setting .RECIPEPREFIX causes the prefix to be inserted into the macro argument.

The attached "prefix.make" demonstrates this behavior.
"prefix.log" is the output.

I tried several different prefix characters with the same result.
