Before: static inline void silk_nsq_del_dec_scale_states( const silk_encoder_state *psEncC, /* I Encoder State */ ); After: static inline void silk_nsq_del_dec_scale_states( const silk_encoder_state *psEncC, /* I Encoder State */ ); (here's a paste in case bugzilla mangles the long lines in "Before" <https://pastebin.mozilla.org/3390092>. Note how the end of the comment gets wrapped even though it would fit just fine on the same line.
Fixed in r194493: clang-format will just replace whitespace with one space character instead of breaking the line, if it results in a line fitting in the column limit.
