 * this lex script used to use characters also in use
 * by strftime() (which we want to use for custom
 * time formats in replies and templates). to circumvent
 * this we have to play a little bit with states.
 *
 * these are the characters we also want to use in the
 * %D time customizer:
 *
 * %a %A %b %B %c %C %d %H %I %j %m %M %p %S %w %x %y %Y %Z
 *
 * you can use these characters too, but don't forget to
 * prepend them with the <S_NORMAL> state.
 *
 * also there is also work around for resetting the state
 * (firsttime variable). this assumes that yylex() will
 * always return to S_NORMAL after quote fmt parsing is
 * done.
