Subject: move the main terminal initialization functions, aside from initscr(),
X-Git-Tag: v1.3.4~40
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=8aaf03000b3e797b479fc250b396c7155e05ed25;p=nano.git

move the main terminal initialization functions, aside from initscr(),
into a new terminal_init() function, and convert nano to use it; also,
when reloading the newly spell-checked temporary file in
do_alt_speller(), call terminal_init() to make sure that all the
original terminal settings are restored, as a curses-based alternative
spell checker (e.g. aspell) can change them
