Why don't you just do it in C? For example, use strcspn/strchr to find the
length of the next word, and then use this to print it:

	av_log(..., "%.*s ", length, str);

sed is standardized; if you carefully adhere to the standard, you can do
pretty advanced stuff. Not that I think this is a good idea, it would be
unreadable.

Also, I do not believe that printing one option per line is a good idea; my
usual build have 36 build options, mostly --enable-foo: that is exactly the
size of most of my work ttys.

I can suggest this: replace "--enable-foo" by "+foo", and wrap to 76
columns.
