32431cddf8 files: block the resizing signal while reading from an external command 
A SIGWINCH somehow causes the input stream to see EOT, with the result
that any remaining output of an external program would be lost.

This fixes https://savannah.gnu.org/bugs/?56038,
and fixes https://savannah.gnu.org/bugs/?56033.

8e302738e8 bindings: recognize the ^W^Y and ^W^V legacy keystrokes again 
The keystrokes are recognized and acted upon, but they are not visible
in the menu nor in the help text, and they cannot be rebound.  They are
there just to avoid frustrating the muscle memory of long-time users.

This fixes https://savannah.gnu.org/bugs/?56002.

b0c9809a2e speller: block the resizing signal also during an integrated spell check 
Because somehow something goes wrong when SIGWINCHes are handled while
reading from a pipe.

This fixes https://savannah.gnu.org/bugs/?56011.

Bug existed since version 2.4.2, commit 75d64e67.

e5a8c35104 feedback: show a message while executing an external command 
Some commands can take a little while to execute; showing just the prompt
during that time could give the impression that nothing is happening.

This addresses https://savannah.gnu.org/bugs/?56041.

7ad232d714 files: initialize a variable before referencing it 
The lack of initialization caused a nasty bug on some targets (such as
ARMv7) which would make it so that ^S would just say "Cancelled".

While x86 (both 64 and 32 bits) seems to initialize 'response' to zero or
a positive number, ARM does not, and there is usually a negative value in
its place, which triggers the 'if (response < 0)' check and, as a result,
the code says "Cancelled".

This fixes https://savannah.gnu.org/bugs/?56023.

3f695b8fb7 speller: resizing can happen also when configured with --enable-tiny 
When nano was configured with --enable-tiny --enable-speller, the
block_sigwinch() function should be available, to mask SIGWINCHes
during a spell check.

f58869d072 tweaks: put the unblocking of SIGWINCHes in a better place

978c121de1 speller: block the resizing signal again during an external spell check 
Somehow a SIGWINCH pushes nano past the wait() in do_alt_speller(),
even though the external spelling program hasn't finished.
