but, 43.45% of users will simply want to change the format and get rid
of "# eww" at the end to see more of the title! :)

specifying a format string is extremely common in many packages out
there for things like this, and is, in my opinion, much more
user-friendly: to change that format with a function, one has to study
eww's api for obtaining title and url, and write a non-trivial piece of
elisp, probably (although admittedly not necessarily) outside the
customization interface.

in other words, i find the format string option as natural and common as
the nil and t ones (which, in a way, are also redundant and could be
removed, since it's trivial to write a function for them).

but i'm probably exaggerating: people will simply copy and paste the
relevant piece of elisp in their init files and call it a day.  so i'll
stop the bike-shedding now :)

cheers,
jao
