@ -65,6 +65,13 @@ The resulting glob is treated as a single argument. For example,
[[ -n *.c(#qN) ]] tests whether there are any .c files in the current
directory.
In prompt strings, the %N(l.true.false) conditional (line length) and
the %N<..< and %N>..> truncation operators now accept negative values
of N, which count the remaining space to the opposite margin (positive
values of N still count the space used since the start of the prompt).
In PS1 and PROMPT, this counts to the right margin, whereas in RPS1 and
RPROMPT, it counts to the left margin (not to the opposite prompt).
