I've made the following API changes to stuff that's also in GNU Emacs:
scroll-up/scroll-down take a second optional argument, WINDOW.
commandp takes a second optional argument, CALL-INTERACTIVELY, which
indicates whether the given item can be executed by `call-interactively'
(normally, the return value indicates whether the item can be executed
by `command-execute'; this includes vectors and strings, which are not
allowed by `call-interactively'). this is a clean way of determining,
for example, how to execute a callback in a menu spec or the like --
such callbacks are defined as "if an interactive thing, use
call-interactively; else, use eval".
Recently I also added the function
(truncate-string-with-continuation-dots STR END-COLUMN &optional DOTS-STR)
Truncate string STR to end at column END-COLUMN, adding dots if needed.
The dots (normally `...', but can be controlled by DOTS-STR)' will be added
in such a way that the total string occupies no more than END-COLUMN
columns -- i.e. if the string goes past END-COLUMN, it will be truncated
somewhere short of END-COLUMN so that, with the dots added, the string
occupies END-COLUMN columns.
"columns" in here refers to the same thing that
`truncate-string-to-width' deals in, i.e. "display columns" where
Japanese characters get two.
