Doc build: circular dependencies dropped?

[Colin Campbell]

I just, for the sake of housekeeping, did a source code update with 
lily-git, nuked my /build, and rebuild ab initio.  The binary build 
didn't seem odd, but the doc produced the following (many similar lines 
snipped for brevity):

> make[3]: Circular web.texi <- macros.itexi dependency dropped.
> make[3]: Circular web.texi <- translations.itexi dependency dropped.
> make[3]: Circular out-www/notation.texi <- notation.tely dependency 
> dropped.
> make[3]: Circular out-www/usage.texi <- usage.tely dependency dropped.
> make[3]: Circular out-www/notation.texi <- macros.itexi dependency 
> dropped.
> make[3]: Circular out-www/notation.texi <- translations.itexi 
> dependency dropped.
> make[3]: Circular web.texi <- macros.itexi dependency dropped.
> make[3]: Circular web.texi <- translations.itexi dependency dropped.

AFAICS, the resulting image is current and correct, so if there is a 
problem, lilypoond seems to manage anyway.

Cheers,
Colin
