2.6.2 Brace expansion

Mosmake supports "brace expansion" similar to what not too ancient Unix shells implement: Instead of

myprog: foobar foobaz foofum blarp gargle %PROGRAM

you can write

myprog: foo{bar,baz,fum} blarp gargle %PROGRAM

This does not look impressive, but it can be used with good effect to improve legibility of `Dependencies' files in a multi-directory setting. See section 2.10 Multiple directories.

Brace expansion also nests:

myprog: foo{ba{r,z},fum} blarp gargle %PROGRAM

though it is hard to imagine a case where it would not lead to "write-onlyness" of the `Dependencies' file rather than simplifying it.
