I recently got my hands on version 17 of the rand editor
and discovered that bullet characters were not supported
for terminals defined by termcap. Here is a fix that produces
a hair cross for termcap terminals. This fix also works for e14
and e15.
I have defined a new string in termcap "bu". If this string is
defined it will be used for drawing a bullet, otherwise '#' is
used.
Here are some examples of bullet definitions:
ambassador genie etc. :bu=\177:
vt100 :bu=^Na^O:ti=\E)0\E[?7l:te=\E[?7h:
perkin elmer 1100 :bu=\E\177:
The definition for vt100 is a bit tricky. The initializing sequence "ti"
selects a convenient alternative character set. The bullet string prints
the 'graphic' version of the letter 'a' (which should be a small square).
(The escape sequence \E[?7l is unrelated: it turns of line wrap around,
because our vt100-look alikes can't handle wrap around at high speed).
I have also redefined <CTRL-B> to mean backtab as "-WORD" was
not implemented.
