Hello, mutt.
I'm using mutt 1.5.23.
The default value of the configuration variable index_format is
"%4C %Z %{%b %d} %-15.15L (%?l?%4l&%4c?) %s".
My personal value is similar. The construct "(%?l?%4l&%4c?)" puzzles
me. The parentheses are literal characters, but what do all the ?s
mean? In practice, this displays the number of lines in the email, what
one would expect from a simple %l. I also have the feeling that the &
is not a literal character either. What does it mean?
I've looked in the manual, at the section documenting index_format, but
the ?s aren't explained there. I've also checked the printf(3) man
page, but there isn't a single ? in it.
Elucidation would be much appreciated. Thanks!
