OK.

Er, the WS was unintentional. Sorry! I can do a bit of other tidying
up on that code, too.

Presumably truncating the number to 99%, except when the window is right
at the bottom of the buffer. The rounding up to 1% is already done by
the SW.

I'm not sure that's the Right Thing. This would take up 7 characters +
at least one space (compared with the current 3 characters + at least
one space for "%p") for "99-100%". That's an awful lot of mode-line
space. I would be tempted to scale it back to 6 characters (for
"54-59%") which is the "usual" maximum width, and take the hit when we
reach "99-100%", by expanding to 7 characters then.
So, the range of formats we'd deal with would be:
"All "
"0-5% "
"4-11% "
"31-38%"
"99-99%"
"99-100%"
, the last one happening only when EOB is visible in the window. This
doesn't take up any more space than my proposed "99%-Bot", which is also
7 characters.
Somehow I think even "100-100%" might be possible, if the window were at
EOB, and the buffer were narrowed to zero characters (if that is
possible - I'm not sure it is). Or, maybe that would be handled by "All
".
I haven't had time to make any changes this evening - I've been working
on the code to select the "percentage offset" formula by a customisable
variable. Maybe we can finalise this change by the weekend.
