                           READLINE PATCH REPORT
                           =====================

Readline-Release: 8.2
Patch-ID: readline82-005

Bug-Reported-by:        Simon Marchi <simon.marchi@polymtl.ca>

Bug-Description:

If an application is using readline in callback mode, and a signal arrives
after readline checks for it in rl_callback_read_char() but before it
restores the application's signal handlers, it won't get processed until the
next time the application calls rl_callback_read_char(). Readline needs to
check for and resend any pending signals after restoring the application's
signal handlers.

Patch (apply with `patch -p0'):
