acid \B format prints 1 garbage character after fmt
e.g.:
acid: 0xe\B
0b00000000000000000000000000001110p

fix by using %b format (which itself needed
a fix to print 0b as prefix if FmtSharp is set).

a clean comple requires this addition to libc.h:

/n/sources/plan9//sys/include/libc.h:177,184 - libc.h:180,189
