I use terminals with columns varying from 110 to 150 chars. this is what my
status line looks like:
-------
-------+[1] JED 0.99.15sau1 | config.sl (SLang) "config.sl":1/659,1
[/u/lloyd1/sdi/.jed/]--------------------
-------
using " JED %v | %b (%m%a%n%o) \"%f\":%p [%d]" as status line.

BTW, the idea of truncating the path is not mine, I took it from the patch
posted by Joachim Schmitz. I simply dropped the system dependent path scan.
Even for me 20 chars are too few (/home/sauro/ are already 12 chars!).
Maybe instead of add such complexity to the status line parser, we can
define a variable to let the user set the maximum length, much like
LINENUMBERS is handled.

I didn't add support for %F to keep the patch as smaller as possible, and
because this way you use always a pointer to already allocated buffers,
instead of copying data to a maybe too small buffer. (Yes, I use already the
buf variable when I truncate the
path, but at that time I now I will not use more that 20 characters).

I prefer to post these patches here, maybe somebody else has a better idea,
or find some issues, before it goes to the standard distribution. 
Maybe John will tell us what he prefers.

Later,
